A compression test and recrystallization simulation test of 41Cr4 steel(medium carbon and low alloy steel)had been performed by GLEEBLE 3500 subject to large strain and high temperature, then the volume fraction of recrystallization and true-stress and true -strain was obtained.
8)条件下,在Gleeble-3500试验机上进行了41Cr4钢的压缩试验和再结晶模拟试验,测得了再结晶体积百分数及真应力和真应变。
In order to establish accurate constitutive equations for hot workings of metals, a large number of constant strain-rate compression tests have been done on thermal-mechanical testing machines (Gleeble-1500 and Formaster-press) using TC11 titanium alloy as testing materials.
为了建立本构方程，必须测量一定温度、应变速率范围内的流动应力值，这通常是由压缩试验来完成的。
