Published: September 2024

The low ability to write procedure texts for making eco-prints for students in grades V and VI is caused by several things that must be observed. This is due to students' lack of understanding of procedural texts, difficulty communicating knowledge in written form, and difficulty composing effective sentences. This research aims to analyze Eco-print exploration activities as an effort to improve writing skills based on project-based learning (PjBL) integrated with Tri-N (niteni, niroake, nambahi). Tri-N concert encourages students to have the ability to observe and scrutinize an object or the stages of the Eco-print process. Then, imitate with a bank that will eventually grow creativity and innovation. This research uses the narrative method to describe the steps of making eco-print, which serves as teaching material to improve students' writing skills. The data collection technique in this research is using observation, interview and documentation techniques. The research findings show that Eco-print exploration activities with the stages of the work creation process are able to explore, narrate the stages, and ultimately foster the ability to write a narrative based on project-based learning (PjBL) integrated with Tri-N (niteni, niroake, nambahi). Through the narrative approach, it can improve students' writing skills, especially in terms of writing descriptions and creativity. The implications of this study highlight the potential of using hands-on activities, such as eco-print making, to improve students' writing skills and enhance their understanding of the writing process.

This research uses experimental research methods for processing mask waste using the method of immersion in 32% HCl solution and immersion in 98% H2SO4. Fifty grams of mask waste were soaked in 1000 ml of each acid solution for periods of 1, 2, 3, and 4 weeks, with four replications for each time period, and water used as a control. After soaking, the masks were dried and re-weighed to assess weight loss. The data were analyzed using T-tests and ANOVA with SPSS 26. Results showed that after 4 weeks, H2SO4 reduced mask mass by 26%, while HCl achieved a 22% reduction. In the first week, H2SO4 reduced the weight by 3 grams, increasing to a total reduction of 13 grams by the fourth week. Similarly, HCl reduced the mask weight by 2 grams in the first week, with a total reduction of 11 grams by the end of the experiment. The findings suggest that H2SO4 is more effective than HCl in degrading disposable mask waste, offering a potential solution for managing mask waste environmentally.

Intensively Quenched Steels for Stronger Parts
Authors: Aronov Michael , Rylicki Ed , Pedder Chris 
Published: September 2024

Abstract
An intensive quenching (IQ) process is an environmentally friendly method of hardening steel parts. Digitally controlled, IQ employs highly agitated and directed water flow as the quenchant. An extremely high cooling rate applied uniformly over the entire part surface area induces high surface compressive stresses which prevents part distortion and cracking while forming a very fine microstructure. The fine microstructure results in better mechanical properties compared to properties imparted by conventional oil or polymer quenching. The improved mechanical properties enable engineers to design stronger steel parts for higher power density mechanical systems often using steels containing a less amount of alloying elements or using less expensive plain carbon steels. A broad and deep body of knowledge documents IQ’s ability to tailor a steel component’s microstructure to improve steel parts mechanical properties and performance. A sampling of data will be presented including surface and core hardness, tensile, yield and impact strength, elongation and reduction in area, residual surface compressive stresses for through hardened steels and the carburized grades. IQ systems can be readily “dropped in” to existing steel processing facilities or integrated into next generation heating and cooling systems through teamed relationships with equipment makers and part manufacturers seeking a sustainable future.
Influence of Time and Temperature on Decarburization Rates for AISI 52100 Steel
Authors: Carragher Matthew , Brody Harold , Frame Lesley 
Published: September 2024

Abstract
Decarburization of steel parts during heat treating results in a lower surface hardness, undesirable residual stress profiles, and poor part performance. Significant effort has been made towards preventing decarburization and determining the impact of annealing time and temperature on decarburization rate. Much of the published research has focused on medium carbon steels, ranging from 0.3wt% C to the eutectoid composition. The goal of the current research is to determine decarburization rates for steels with carbon concentrations above the eutectoid concentration. AISI 52100 steel was heated in air for 12, 24, and 36 hours at three temperature ranges (below A1, above Acm, and between A1 and Acm). Optical microscopy was used to determine the carbon concentration as a function of depth from the surface. The diffusion coefficients of carbon in austenite and ferrite plus cementite phase assemblages were calculated. These diffusion coefficients can be used in a finite difference simulation to predict decarburization at different temperatures and times.
Microstructural Development and Fracture Behavior after Rapid Tempering in the Tempered Martensite Embrittlement Regime of 1045 Steel
Authors: Jacobs M.J. , Cryderman R.L. , Findley K.O. , Speer J.G. 
Published: September 2024

Abstract
Quenching and tempering (Q&T) allows a wide range of strength and toughness combinations to be produced in martensitic steels. Tempering is generally done to increase toughness, although embrittling mechanisms result in temperature ranges where strength and toughness may decrease simultaneously. Tempered martensite embrittlement (TME) represents one such mechanism, associated with the decomposition of retained austenite and precipitation of cementite during tempering, usually between 250 and 450 °C. The use of induction heating allows for time-temperature combinations, previously unobtainable by conventional methods, that have been shown to improve properties. The present work shows a beneficial effect of rapid tempering in alloy 1045, with an increase in energy absorption of about 50% when measured at room temperature via a three-point bending fracture test in the TME regime. Phase fraction measurements by Mössbauer spectroscopy showed that increased energy absorption was obtained despite essentially complete decomposition of retained austenite during tempering. Scanning electron microscopy (SEM) investigation of the carbide distribution showed refinement of the average carbide size of approximately 15% in the rapid tempered conditions. SEM characterization of the fracture surfaces of the rapid tempered three-point bend samples showed that, despite an increase in energy absorption in the TME regime, increased microscopic ductile fracture appearance was observed only at the highest test temperature.

Authors: Zeng Qianchen , Christiansen Thomas L. 
Published: September 2024

Abstract
This study investigates the heat treatment response and microstructure evolution of high-carbon steels for additive manufacturing. Moreover, the role of nitrogen as an interstitial alloying element is addressed. Stainless steel 440C, cold-work D2, hot-work H13, and T15 high-speed tool steel overspray powders from spray forming were investigated. The thermal behavior of these materials was examined using a thermal analyzer that combines calorimetry and thermogravimetry. Additionally, interstitial alloying with nitrogen was performed in-situ to understand its influence on thermal behavior. The (near-)equilibrium nitrogen solubility in 440C and D2 in contact with flowing N2 gas was recorded as a function of temperature through the interval 1200 to 800 °C. The microstructure of the steel powders was characterized by light optical microscopy and X-ray diffraction.
The potential of nitrogen alloying and the importance of optimized heat treatment protocols are emphasized with respect to high-carbon steels in additive manufacturing applications.

Abstract
Quenching is one of the primary processes to improve mechanical properties in steels, particularly hardness. Quenching is well established for different geometries of individually treated steel components; while in-steam quenching of large diameter continuously cast steel bar has several specific features which are difficult and costly to experimentally optimize. The end-quench Jominy test has been used extensively to study the hardenability of different steel grades. Different numerical, analytical, and empirical models have been developed to simulate the Jominy process and to understand quenching of steels. However, it is not straight forward to translate experimental data from Jominy test on instream quenched large diameter continuously cast products.
Therefore, in this work, coupled thermal, mechanical, and metallurgical models were used to simulate the end-quench Jominy test and in-stream quenched industrial round billets with a goal to obtain similarity of experimental structure and properties for both quenched products. For this purpose, finite element analysis (FEA) was employed using the software FORGE (by Transvalor). Used thermophysical properties were generated by JMATPro software. The evolution of microstructure during quenching and resulting hardness were simulated for AISI 4130, and AISI 4140 steel grades. The cooling rates at different positions in the Jominy bar were determined by simulation and compared to experimental. After verification and validation, the FEA simulation was utilized to predict different phases and hardness at different conditions in industry produced round billets. Additionally, relations between Jominy positions and radial positions in the billet were established allowing us to predict structure and properties in inline quenched continuously cast bar having different diameters.

Abstract
The automotive industry has searched for alternatives to reduce the weight of vehicles without neglecting the user’s safety by using new materials. Advanced high-strength steels of complex phases are used in structural applications requiring good performance and reducing the weight of vehicles. However, these steels have shown edge cracking, known as fissure, during processing, which has become a challenge for steelmakers and other companies that rely on them to manufacture structural components. Such defects can be associated with the interaction between the different microstructural constituents of the steel, such as various phases and precipitates generated during its processing to achieve the required mechanical properties. The present work presents the studies evaluate the effect that processing and chemical composition exerts on edge cracking in complex phase steels of grade 800 MPa produced by different steelmaking routes.
