利用Gleeble3500热模拟试验机对403Nb马氏体叶片钢进行二道次高温热压缩试验，对不同温度、应变速率、道次间隔下发生的静态再结晶进行了研究和计算，得到403Nb静态再结晶、静态再结晶激活能和静态再结晶晶粒尺寸模型。

The twopass hot compression experiment of 403Nb leaves steel was carried out by using Gleeble3500, and its static recrystallization was studied at different temperature,strain rate and pass intervals to find out the static, recrystallization model, static recrystallization activation energy and static recrystallization grain size model.
