Effects of solutes and temperature on high-temperature deformation and subsequent recovery in hot-rolled low alloy steels

The high temperature deformation behavior, kinetics of recovery and onset of recrystallization in ternary Fe-0.1%C-X (X = Mn, Si or Al) alloys have been investigated. The alloys were hot-deformed to a strain of 0.25 at various temperatures from 850 °C to 1100 °C, at a strain rate of 1 s−1. The effect of solutes and temperature on the flow stress was examined. In addition, stress-relaxation experiments were performed to quantify the restoration …
