摘要
利用Ｇｌｅｅｂｌｅ－１５００热模拟试验机，研究了９Ｃｒ－１Ｍｏ－Ｖ－Ｎｂ－Ｎ铁素体耐热钢在８５０℃～１２５０℃，接近实际生产变形速率时的高温塑性，做出塑性图和再结晶图。并通过分析真应力—真应变曲线。
The true stressstrain curves(from 850 to 1250)and plasticity at high temperature of ferritic stainless steel 9Cr1MoVNbN at temperature had been studied by using Gleeble1500 thermomechanical simulatorThe plasticity diagram and recrystallization diagram were also plottedAdditionally,the deformation resistance expression was regressed by Marquardt method
