Published: June 2020

Abstract
Dissimilar friction stir welding between AA2024-T3 and pure copper was attempted with threaded tool pin. After annealing of copper, the flowability, joint appearance, material sticking with tool was reduced and maximum tensile strength of the joint was achieved for the joint prepared at 470 rev/min tool rotation and 63 mm/min weld speed as compared to the other tested conditions. In the weld stir zone of this joint, presence of copper in dispersion was noticed. Joint failure was observed beyond the weld nugget from the annealed copper side and presence of numerous fine dimples on fracture surface was observed.

Published: June 2020

Abstract
In this theoretical work, the effect of support stiffness in controlling the nonlinear vibration of loosely supported cross-flow heat exchanger tube and support-impact forces is studied. The bending of slender heat exchanger tube is modelled using Euler-Bernoulli beam theory. The cross-flow induced forces on tube are modelled using quasi-steady flow model whereas the loose support is modelled with trilinear spring model. The Galerkin discretisation and time integration are used to solve the nonlinear governing differential equation of motion. From the results, it is observed that with the reduction of support stiffness, the chaotic motion of the tube gradually changes to periodic motion, the drastic changes in the acceleration of the tube during its motion reduces, and also the magnitude of the contact forces greatly reduces. Thus, if the support is made of low stiffness material or placing a low stiffer buffer layer over stiff support, the vibration and impact forces can be significantly reduced..

Authors: Deshmukh S S , Goswami A 
Published: June 2020

Abstract
In today’s scenario every manufacturing industry tries to achieve maximum productivity and profit. Manufacturing large number of components within less time helps in increasing the productivity and profit. Hot Embossing is a manufacturing process chiefly used for development of micro-structures on polymer. The parameters considered in this study are the embossing temperature, applied load, embossing time, and de-embossing temperature. The optimization has been carried out with help of Taguchi method for reduction of deviation in width of embossed micro-structures. The Taguchi L9 orthogonal array has been used for collection of data and ANOVA has been performed to find out the percentage contribution of each process parameter of Hot Embossing. ANOVA result reveals that embossing temperature has major contribution of 45.92% as compared to other process parameters. After optimization the working values for different process parameters are embossing temperature = 115°C, applied load = 1.5 tonne, embossing time = 8 minute and de-embossing temperature = 40°C. At an optimum level deviation in width of embossed micro-structure from dimension of mold is only 1.72 μm which is less than the value obtained in each experimental run.

Published: June 2020

Abstract
Tool manufacturers’ aims to produce quality tools to with stand higher cutting forces, thermal resistivity with increased wear resistance to improve tool life and to produce better surface finish maintaining dimensional accuracy of the finished product. The paper analyses the machining performances of single point cutting tool made from high speed steel and tungsten carbide in dry machining of mild steel and aluminium. Varying cutting speeds, feed rates and depth of cuts were taken into consideration for the experimental performance, using lath tool dynamometer. The data obtained from the experiments are used for the static, modal and steady state dynamic analysis using FEA package ABAQUS solver. From the static analysis, it was found that WC has a higher stiffness and durability as compared to the HSS. The natural frequencies and the mode shapes of the HSS and WC tools were identified and plotted. The analysis showed WC tool has higher natural frequencies as compared to the HSS tool for each of the six mode shapes. The dynamic analysis of the tools showed the deformation was least for WC. The stress induced in WC was found to be around 50% of that of HSS and the factor of safety was almost double to that of HSS. Thus this paper shows that static and dynamic performance analysis of the WC tools is better than the HSS tools.
Flame analysis for prediction of thermocouple temperature and quality of sponge iron at TATA steel long products limited

Published: June 2020

Abstract
The temperature profiles of the gas and charge in a coal-fired rotary sponge iron kiln affect both the iron ore reduction process and accretion formation. The temperature profile of charge is estimated from the eleven thermocouples (TC1-TC11) placed along the 80 m length of the kiln. The quality prediction models are heavily dependent upon the accuracy of the measurement of TC10. However, slowly, as the kiln’s campaign life increases TC10, and other thermocouples too, get corrupted due to deposition of material (accretions) on the thermocouples. At the beginning of the campaign, however, there is no accretion on TC10. In the present work, an attempt is made to directly correlate flame characteristics with TC10 and with quality of iron produced so that when TC10 is corrupted due to accretion or breakdown, we can still survive by using flame characteristics as a guide to control quality. The flame inside the rotary kiln has been analysed by using image analysis procedures for the first time in a sponge iron plant. The flame’s estimated average temperature and pixel intensity information are correlated with (a) the temperature measured by the thermocouple TC10 (which is installed at a distance of 20 m from the rotary kiln outlet hood) and (b) with quality of iron produced. It is found that use of average flame temperature for quality prediction has several advantages in terms of increased accuracy of prediction and quicker response time of flame to short-time changes in coal quality (particle size, moisture, ash content, etc) whereas TC10 thermocouple takes much longer to reflect these changes due to slow process of heat transfer to charge. In addition, the adverse effect of accretion formation on TC10 for quality prediction has been overcome.

Published: June 2020

Abstract
Flat plate heat pipes (FHP) can transport high heat fluxes liberated by electrical and electronic equipment. Wick structure plays an essential role in the performance of the heat pipe. The wick structures are made of materials like sintered metal powder, foam, screen mesh, different shapes of grooves, or any material capable of producing capillary force. Generally, wick structures can be inserted or fixed easily inside the heat pipe enclosure. There are cases where one cannot insert or fix the wick structure, such as tubes with several bends and varying cross-sections. Therefore, this study directed to develop a wick structure inside the enclosure through an electrochemical process. As a preliminary study, a hierarchical wick structure is formed at the inner side of the flat heat pipe, and the performance is studied. This method can be applied to create dendrite copper wicks with the required porosity, pore size, and wick thickness by adjusting the electrolyzing conditions. In this study, a flat heat pipe is fabricated with copper hierarchical wick structure, and the performance analyzed over another heat pipe without wick and with screen wick.

Published: June 2020

Abstract
Surface integrity is one among the prime quality features of turned parts. In the present research work, surface residual stress generated during parallel turning is analysed numerically using finite element method based software. Parting of cut-chip from uncut-work material is dealt by Johnson-Cook criteria. Tool-chip friction was modelled by penalty contact method. Cutting tool parting distance is an important process parameter in parallel turning. The main objective of the current research work is to evaluate the significance of parting distance on axial and circumferential surface residual stresses induced on machined work surfaces. The analysis revealed that with the increment in parting distance, the surface integrity raised. When the distances was raised from 0.4 to 0.8 mm, for a cutting velocity of150 m/min and feed 0.2 mm/rev the axial and circumferential residual stresses elevated by 34% and 33% for surface machined by second tool. For all chosen parting distances, the stresses raised with the increase in cutting velocity. Parallel turning was advantageous in increasing the machined surface integrity.

Abstract
In this study, characteristics of two different resole based phenolic resin being used in aerospace application were investigated. Phenolic resins were advanced by conditioning to bring down its point of trouble. At this stage both resins were separately impregnated with PAN based carbon fabric as reinforcement and evaluated their rheologyproperties. Residues of free phenol, free formaldehyde and sodium content in resins were estimated for both the resins and compared. Also other properties such as neat resin cure characteristics, resin characteristic frequencies, molecular weight distributions, char yield of resins were evaluated and compared. A conclusion is drawn from the test results that char yield is affected by purity of phenolic resin viz presence of unreacted free phenol and free formaldehyde. Also viscosity plays a vital role in wetting of the reinforcement resulting in better interlaminar shear properties.

Published: June 2020

Abstract
We report here a facile synthesis of Gadolinium doped titanate (GDT) nanocomposites (NCs) and their impedance, total current gain in the various concentrations of doped and undoped gadolinium to the titanate nanomatrix was investigated. GdTiO3 NCs synthesized by co precipitation method using CTAB (cetyl trimethyl ammonium bromide) as capping agent triethyl amine under acidic condition at high temperature. Gd was doped (10-40 % molar wt) ratio, characterized by SEM (scanning electron microscopy), XRD (X-ray diffraction spectroscopy), UV Visible, CV (cyclic voltammetry) spectroscopic analysis. SEM crystal morphology indicated Gd x (TiO3) 1-x was tetragonal close packing with the distribution of overlay of Gd is 50 nm, CV characterization revealed the oxidation potential of GdTiO3 was + 0.34 eV. The aligned GdTiO3showed linear increase in the resistance with the different thickness of the pellet made from powdered NCs. Significant increase in the conductivity is due to varied thickness, decease in the particle size, distinct grain boundaries. The modulus of the complex impedance (Z* ω) with respect to different current and voltage gain were measured by different size of the pelletized nanomaterials (∼15 mm diameter, ∼1-5 mm thickness, pressure of ∼ 0.4 GPa) and the phase angle θ measured with different frequency range from 40 Hz to 2 MHz. The variation in the impedance (real and imaginary) depends on the grain boundary and grain size contribution at lower and higher frequencies. The conductivity due to grain (σg), grain boundary (σgb), calculated from the values of Rg and Rgb (resistance at grain and grain boundary) and the specific grain boundary (σsgb) was calculated for the nanocomposites.

Abstract
The inhibition performance of 2-meracaptobenzothiazole on the corrosion of 316 austenitic stainless steel in 3M HCl, mild steel in 1M HCl and 1060 aluminium alloy in 2M H2SO4 solution alloy was studied by coupon measurement. Results showed the compound performed more effectively on the 316 steel with average corrosion inhibition performance result of 90% followed by the aluminium alloy with average inhibition performance value of 70%. 2-meracaptobenzothiazole performed poorly on mild steel with average inhibition performance results of 55% at low concentration and results below 0% and high inhibitor concentrations. Statistical data through showed that inhibitor concentration only influenced the inhibition performance of 2-meracaptobenzothiazole. Inhibitor concentration and exposure time were statistically relevant to the inhibition performance of 2-mercaptobenzothiazole on mild steel at varying degrees while both inhibitor concentration were statistically irrelevant to the inhibition performance of 2-meracaptobenzothiazole on 1060 aluminium alloy. Adsorption isotherm studies showed SD adsorption on the metallic alloys aligned with Langmuir, Frumkin and Freudlich adsorption with general correlation coefficient above 0.9991.

Published: June 2020

Abstract
Concrete filled tubular section (CFT’s) and self-compacting concrete (SCC) is the ideal material for achieving goals like strength, durability, toughness, economic, controlling thermal cracking, plastic shrinkage, etc. for high rise buildings. The CFT’s were filled with the self-compacting concrete (SCC) and Normal Concrete (NC) with the different eccentric loading on the sections. Normal Concrete is forming the problems due to its less workability and filling concrete in the smaller cross-sections or dense reinforcement. CFT’s carries higher loads as compared to conventional reinforced concrete and steel columns. For the economic aspects, the CFT’s are mainly used for the High Rise Building (HRB) due to its properties. In earlier research show that the different ratio of the of D/t and L/D section with various types of concrete with or without using of admixture was used in the study
