摘要
研究了高温条件下00Cr17Ni14Mo2和00Cr19Ni10两种易热部件用奥氏体不锈钢的断面收缩率与应变速率的关系。结果表明,00Cr17Ni14Mo2钢的显微组织由晶粒较大的奥氏体组成,00Cr19Ni10钢的显微组织由粗大的奥氏体和少量分布于奥氏体晶界及晶粒中的铁素体组成。00Cr17Ni14Mo2钢在不同应变速率条件下,断面收缩率随变形速度的增大先上升后下降,应变速率对其断面收缩率的影响较小。00Cr19Ni10钢在不同应变速率条件下,断面收缩率也是随变形速度的增大先上升后下降,但是应变速率对其断面收缩率影响较大,断面收缩率随应变速率升高而增加。
The relationship between the section shrinkage rate and the strain rate of two kinds of 00Cr17Ni14Mo2 and 00Cr19Ni10 austenitic stainless steel in high temperature condition was studied. The results show that the microstructure of 00Cr17Ni14Mo2 steel is composed of larger austenite grains, and the microstructure of 00Cr19Ni10 steel is composed of coarse austenite and a small amount of ferrite in austenite grain boundaries and grain. Under different strain rates, the section shrinkage rate of 00Cr17Ni14Mo2 steel increases first and then decreases with the increase of deformation velocity, and the strain rate has little effect on the shrinkage rate; and the section shrinkage rate of 00Cr19Ni10 steel also increases first and then decreases with the increase of deformation velocity, but the strain rate has a greater influence on the section shrinkage rate when the strain rate increasing.
