PingliMAO %A KeYANG %A GuoyueSU %J 材料科学技术学报 %D 2003 %I %X The hot deformation behavior of an as-cast 0Cr17Mn14Mo2N duplex stainless steel has been studied by hot compression test at the temperature range from 1000℃ to 1200℃, and the strain rates are 0.1 s-1, 1 s-1 and 5 s-1,respectively. It was found that during hot deformation there is only dynamic recovery taking place within the δ-ferrite phase, but the γ-austenite phase undergoes dynamic recrystallization. The activation energy of the steel for hot compression is estimated to be 480 k J/mol. %K Hot deformation %K Duplex stainless steel %K Microstructure
