Strain-rate dependent material properties of selective laser melted AlSi10Mg and AlSi3.5Mg2.5
Authors: Lutz Andreas , Huber Lukas , Emmelmann Claus 
Published: June 2020

Abstract
This paper investigates the mechanical properties of two selective lasermelted aluminum alloys (AlSi10Mg and AlSi3.5Mg2.5) under high strain-rate uniaxial loading. Accelerated tensile tests were performed under various strain-rate decades (.ε = 4.7 × 10-3 up to 250 s-1) to determine the load-speed-specific changes in the mechanical properties. As a result of the primary laser-based shaping process, the microstructure and characteristics change was entirely comparable to the conventional manufacturing of aluminum parts. Based on an ultrafine microstructure, parts achieve high strength along with a brittle fracture behavior. Modifications for applications requiring high ductility (e. g., the crashloaded structural parts of a car body) can be made through specific heat treatment strategies. The experimental results demonstrate that a significant increase in ductility (factors 4-5) with a concurrent decrease in strength can be obtained compared to the as-built state. In high-speed tests, the tensile strength of both alloys rose strain-rate dependently around 10 %, and the elongation at break increased relatively by ≈ 15 % for AlSi10Mg and ≈ 10 % for AlSi3.5Mg2.5.
Investigation of the influence of heat treatment of cold work steel on coating adhesion under mechanical load between substrate and thin titanium coatings deposited by PVD
Authors: Buttler Torben , Reiter Rolf , Wesling Volker 
Published: June 2020

Abstract
Metastable phases can be shifted to a different state by thermal loads on components. This leads to structural changes and precipitation. Within the scope of this investigation, a coating is applied to a solution annealed and a quenched and tempered substrate of the same chemical composition by means of a cold PVD process. The investigation is based on the process of polymer extrusion without additives. The substrate examined is 1.2379 tool steel. The substrate is used as a screw extruder material and is exposed to operating temperatures of up to 400 °C. A titanium layer is applied which is used in practice as an adhesion promoter and is in direct contact with the substrate. An annealing temperature above 500 °C results in special carbide hardening. These should show a worse layer adhesion than the metal bonds of the solution annealed sample. The aim is to investigate whether a difference is measurable or negligible. The loads during polymer extrusion are simulated by means of bending and pin-on-disk tests. The 3-point bending test simulates the mechanical load during extrusion. The pin-on-disk test simulates the friction between the extrusion screw flank and the extrusion cylinder. The substrate is characterized before and after sample preparation. Wear measurements are carried out using CLSM and SEM. The surface topography is recorded and then evaluated for comparison.

Published: June 2020

Abstract
Metallic coatings which provide a hydrogen diffusion barrier are thought to reduce hydrogen assisted cracking on stainless steel. The influence of a metallic layer on the hydrogen migration of AISI 304 stainless steel was investigated using a commercial electroplating layer of Ni and Au on a thin stainless steel coupon. Phase identification was performed using an X-ray diffractometer to determine the average thicknesses, measured from back-scattered scanning electron images. Regarding the ASTM G148-97 practice, the effective hydrogen diffusivities of AISI 304 austenitic stainless steel, nickel and gold were measured as 7.07 × 10-13, 2.72 × 10-14 and 9.64 × 10-16 m2 × s-1, respectively. In this work, a gold layer was found to be most effective for the prevention of hydrogen diffusion when compared with untreated and Ni-plated 304 stainless steel.

Published: June 2020

Abstract
Fused deposition modeling is one of the most well-known additive manufacturing methods. It might be considered the easiest way to produce particle reinforced composites or unreinforced sheets which are biodegradable and used in the packaging industry as well as for custom products. In this study, polylactic acid (PLA) sheets were produced by 3D printing and thermoformed using a lab-scale thermoforming machine. This article aims to determine the deformation behavior of 3d printed PLA sheets during thermoforming. In addition to experimental work, finite element analysis was performed to investigate the prediction capabilities of Mooney-Rivlin and Ogden models for PLA sheets. In addition, the initial thickness of the sheet was optimized using FEA and a python script to obtain final uniform thickness distribution. Thanks to 3D printing’s capability for printing sheets of variable thickness, sheets of variable thickness were printed to verify the material models. As a result, based on the thickness distribution obtained from the experimental study, Mooney-Rivlin and Odgen material models were found to be inadequate for representing the actual deformation behavior of PLA sheets.

Authors: Ertan Rukiye 
Published: June 2020

Abstract
In this study, the mechanical behavior of titanium (ASTM Grade 2) alloy sheet, resistance spot welded with 5754 aluminum alloy, was investigated with respect to nugget formation and mechanical properties. The welding operations were performed using resistance spot welding at various welding currents (10, 12.5 and 15 kA), welding times (10, 15 and 20 cycles) and electrode forces (5, 10 and 15 kN). The weld nugget diameter and nugget center height, hardness, and tensile-shear test results of the welded samples were examined, and the mechanical properties were compared. As a result of the tests, it was seen that the welding parameters have a significant effect on the mechanical properties of the titaniumaluminum alloy welding joints. The tensile-shear load of the resistance spot welded joints increased as the welding current increased, and welding time increased for 15 cycles. On the other hand, when the electrode force increased, the tensile-shear load decreased markedly.

Published: June 2020

Abstract
In this study, the wear and microstructure properties of some coatings produced on Weldox 700 steel were investigated via a high-velocity oxygen fuel (HVOF) technique. For the coating types, NiCrBSi, WCCo and CoNiCrAlY-based coatings were selected. Microstructure and phase formation were examined via scanning electron microscopy (SEM), X-ray diffraction and X-ray energy dispersive spectrometry. Wear tests of the substrate and coatings were made using the ball-on-disc method. It can be seen from the SEM images that the coating layers are metallurgically/ mechanically connected to the substrate and have a mostly homogeneous structure. The hardness measurement was taken from the top of the coatings. The hardness values of the coatings were significantly higher than those of the substrate. The coated substrates exhibit a very good tribological performance compared with the substrate. Depending on the load, the wear rate and coefficient of friction of the coatings were much lower as compared with the Weldox 700 steel substrate.

Published: June 2020

Abstract
In today’s world, reducing fuel consumption is one of the most important goals for the automotive industry. For this reason, weight reduction is one of the main topics in this research and for various companies. In this research, topology optimization was conducted on a suspension arm as a means of ensuring balance in automobiles. Subsequently, the model, formed by topology optimization was filled with a lattice structure and re-optimized by size optimization to obtain optimum dimensions for the model. These operations are described as lattice structure optimization. Additive manufacturing (3D printer) is necessary to produce complex models (after topology and lattice structure optimization). A static analysis of the new models was conducted by using the finite element method, and the results were compared with those of the initial design of the model. As a result of the comparison, positive results were obtained, and it was shown that topology optimization and lattice structural optimization could be used in the design of vehicle elements. According to the results obtained from lattice structure optimization, design structure can be formed more reliably than via topology optimization. In addition, both configurations and layouts of the cellular structures have a special effect on the overall performance of the lattice structure.

Published: June 2020

Abstract
This paper presents the growth kinetics of the boride layer formed on a boronized AISI 316 (X5CrNiMo17-12-2) stainless steel surface. Samples were boronized applying the Ekabor 2™ boronizing agent in an atmosphere controlled furnace at 1073, 1173 and 1273 K for 1, 2 and 3 h by the powder pack method. Surfaces of the samples which have completed the boronizing process were prepared for metallographic examinations. An optical microscope and an integrated image analyzer were used to measure the thickness of the boride layer formed on the surface of the samples. Due to the dual phase structure of the boride layer formed on the steels in order to see these phases in detail, an SEM (Scanning Electron Microscope) image of the sample was taken with the help of the back scattered electrons. In addition, for determination of the elements constituting these phases, elemental analysis was carried out with the help of an EDS (Energy Dispersive Spectroscopy) unit connected to SEM. Then XRD (Xray diffraction analysis) analyses were carried out to understand in detail which phases formed the boron layer. For hardness measurements of boride layers, a Vickers hardness device with 100 g weight was used. Finally, to determine the growth kinetics of the boronized samples, calculations were made with the help of the Arhenius equation and compared with the literature.

Abstract
Ceramic coatings were prepared on the surface of 7050 highstrength aluminum alloy using micro-arc oxidation in an aluminate electrolyte with added graphene. To analyze the surface morphology, roughness, phase composition, and corrosion resistance, scanning electron microscopy, X-ray diffraction, X-ray photoelectron, and electrochemical measurements were used, respectively. The addition of 9 g · L-1 of graphene to the electrolyte decreased the micro-pore size of the composite coatings and improved the density. In addition, with the addition of graphene, the roughness was the lowest, and the corrosion resistance was significantly improved.
