Abstract:
The effect of sintering parameters on the properties of austenitic nickel-free stainless steel was investigated using a rate-controlled sintering approach. This study focused on optimizing sintering parameters, including the influence of different gas atmospheres (argon, nitrogen, and hydrogen) with varying partial pressures of nitrogen. The goal was to explore how these parameters affect phase formation, mechanical properties, and corrosion resistance. Mechanical properties were evaluated using indentation-based methods, providing a comprehensive assessment of hardness and elastic modulus. Additionally, corrosion resistance was studied through electrochemical testing. Simulation results, calculated with Thermocal software, were used to complement and compare experimental findings. The results revealed critical insights into the relationship between sintering atmosphere, phase evolution, and material performance, offering a deeper understanding of how sintering conditions can be optimized for enhanced mechanical and corrosion properties in nickel-free stainless steel.
