采用Gleeble-1500热模拟试验机研究了18Mn-18Cr-0.5N奥氏体护环钢热变形时的力学行为。获得了18Mn-18Cr-0.5N钢的动态再结晶激活能及峰值应力σ_p、峰值应变ε_p与Zener-Hollomon参数Z间的关系式。
The mechanical behavior of 18Mn-18Cr-0.5N austenitic retaining ring steel during hot deformation was studied by Gleeble-1500 thermal simulation test machine. The dynamic recrystallization activation energy and the relationship between peak stress σ_p, peak strain ε_p and Zener-Hollomon parameter Z of 18Mn-18Cr-0.5N steel were obtained.
