摘要

借助 X-射线衍射分析法研究了 0.45% ~1.44%Cu 对(%)：0.068 ~ 0.072C 18.72~19.06Cr 、9.40~ 9.46Ni的304不锈钢-196 ℃低温拉伸应变诱发马氏体相变的影响。结果表明

Cu对304不锈钢-196 ℃应变诱发e马氏体相变有明显的抑制作用;当Cu含量增至1.44%时，在经低温变形的钢中未检测到ε马氏体相变。随钢中Cu含量增加，-196℃ 应变诱发α'马氏体相变倾向降低，致使应变累积到一定程度后，流变应力低于低Cu钢。

Abstract

The effect of 0.45% 〜1.44% Cu on low temperature tensile strain-induced martensite transformation in 304 stainless steel-0. 068 ~ 0. 072C

18. 72 ~ 19.06Cr

9. 40 ~9.46Ni at - 196℃ has been studied by X-ray difi&action analysis. Test results showed that the Cu had obvious depression action to strain-induced e martensite transformation in 304 stainless steel at - 196 ℃

and with increasing Cu content in sted to 1.44% the e martensite transformation was not detected in low temperature deformed sted. And with increasing Cu content in steel the trend of strain-induced α'martensite transformation at- 196 ℃ decreased

led to flow stress lower than that in low Cu content steel after strain accumulated to definite value.
