Description
Summary:► Effect of initial microstructure on warm forming behavior in medium carbon steel. ► The flow stress of ferrite+pearlite is higher than that of martensite at 873–973K. ► Warm deformation promotes tempering and dynamic recrystallization in martensite. Specimens with ferrite+pearlite (F+P) and martensite (M) microstructures were compressed under warm conditions. The flow curves of quenched specimens were below those of annealed specimens at 873–973K (600–700°C) and a strain rate of 0.001s−1. This was due to the tempering and dynamic recrystallization of martensite.
