Abstract:
Stellite 6B superalloy is widely used in the harsh industrial environment, because of excellent wear characteristics, hot hardness, good corrosion resistance, and superior mechanical properties [1-8]. Dynamic recrystallization (DRX) is considered as one of the most important microstructural evolution mechanisms, which is beneficial to obtain fine metallurgical structures, eliminate defects and improve mechanical properties of products [9-14].Hot compression tests were performed on Stellite 6B alloy to study high temperature dynamic recrystallization behavior during thermal deformation. The tests were performed in the temperature 1000 °C, 1050 °C, 1100 °C, 1150 °C and 1200 °C and at the strain rates of 0.001 s−1, 0.01 s−1, 0.1 s−1, 1 s −1 and 10 s−1. Stress-strain curves, constitutive relationship, and the DRX model of the Stellite 6B alloy were investigated. The results showed that the dynamic recrystallization was easily beginning, the dynamic recovery process is inhibited, and the softening effect by dynamic recrystallization is more significant.
