Abstract
Abstract Austenitic Stainless Steels are in great demand and its application has importance in defense, automotive as well as in nuclear industries. Understanding its properties and deformation behavior becomes the key prerequisite to optimize the process parameters for improving the working condition suitable for processing and ensuring safe performance during hot working. The present work focuses on optimizing the mechanical properties such as ultimate tensile strength, yield strength, and % elongation at different temperatures ranging from 750°C to 900°C at an interval of 75°C at two different strain rates (0.1 & 0.001s-1) in three different orientations (00, 450, 900) to the rolling direction. The L18 based design of experiments was used to perform the experiments. The experimental results showed that temperature has a significant effect on material properties. With the increase in temperature, % elongation increases and a considerable decrease in strength was observed. The Ultimate strength, yield strength, and % elongation were optimized using response surface methodology. The temperature found to be the most influencing factor by having a percentage contribution of 64.4% from so obtained ANOVA results.
