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.
