Abstract

Understanding deformation behavior and workability is key prerequisite to optimize process parameters to improve the material processing conditions and confirming safe performance during forming. The deformation characteristics of Inconel 718 and 625 alloys have been investigated using hot tensile tests at temperature range (room temperature to 973 K) at interval of 100 K and at quasi-static strain rate of 0.0001, 0.001, and 0.01 s−1. The experimental findings confirmed that tensile flow stresses are considerably subtle to strain deformation temperature and strain rate. From tensile flow stress behavior, processing maps have been developed using dynamic material model approach at different value of strains. It was observed that the temperature range (T < 550 K) for Inconel 718 and 600–900 K for Inconel 625 for lower strain rate (0.0001 s−1) efficiency were maximum at different considered strain values. The optimum working parameters for both the alloys have been identified.
