Serrated flow behavior and microstructure evolution of Inconel 625 superalloy during plane-strain compression with different strain rates

Strain rate played an important role in the forming process of metal and alloy. In the present work, the effect of strain rate on deformation behavior and microstructure evolution of thermal-rolled Inconel 625 superalloy were systematically investigated by plane-strain compression (PSC) test at 1000 °C, and the strain rate range changed from 1 × 10−3 s−1 to 5 s−1. Obvious serrations occurred in strain rate range of 5 s−1 - 0.05 s−1 and...
