Research on the Rules of Influence of Austempering Parameters on the Tensile Strength and Elongation of ADI

Abstract

select ADI commonly used in engineering, set 15 sets of austempering parameters and research on the rules of their influence on the tensile strength and elongation of ADI. Through the tensile test, use ANSYS Workbench to simulate the process of tensile measurement and compare the experimental data. The results show that: longer austenitizing time leads to smaller tensile strength, whereas the elongation remains unchanged. The tensile strength reduces linearly as the austempering temperature rises while the elongation first increases and then reduces as the austempering temperature rises and peaks at 350°C. The austempering time has little influence on elongation.
