采用Gleeble热模拟试验机,在变形温度900～1050℃和应变量0～0.69条件下对原始等轴组织的0Cr13Ni8Mo2Al钢进行等温恒应变速率(10 s-1)压缩试验,研究了0Cr13Ni8Mo2Al钢变形组织的演化规律。结果表明,在本实验变形条件下,0Cr13Ni8Mo2Al钢在变形过程中没有发生完全再结晶,只发生部分再结晶。当应变量小于0.29时,再结晶非常少;当应变量达到0.29后,再结晶明显增多。当变形温度为900～1000℃时,平均晶粒尺寸随温度的变化较小;在1000～1050℃时,平均晶粒尺寸随温度的变化较大。当应变小于0.29时,平均晶粒尺寸明显地随应变增大而减小;当应变达到0.29时,平均晶粒尺寸缓慢地随应变增大而减小。
The isothermal constant strain rate (10 s-1) compression test of 0Cr13Ni8Mo2Al steel with original equiaxed microstructure was carried out with Gleeble thermal simulator at deformation temperature of 900 ~ 1050 ℃ and strain of 0 ~ 0.69. The deformation of 0Cr13Ni8Mo2Al steel The evolution of law. The results show that under the experimental deformation conditions, 0Cr13Ni8Mo2Al steel did not recrystallize completely during the deformation, and only partial recrystallization occurred. When the strain is less than 0.29, recrystallization is very small; when the strain reaches 0.29, the recrystallization increases obviously. When the deformation temperature is 900 ~ 1000 ℃, the average grain size changes little with the temperature; at 1000 ~ 1050 ℃, the average grain size changes greatly with temperature. When the strain is less than 0.29, the average grain size obviously decreases with increasing strain. When the strain reaches 0.29, the average grain size slowly decreases with increasing strain.
