摘要: <正> 本工作研究Fe-Mn-Al-Cr系亚稳奥氏体区中形变a′马氏体量和形变量的关系以及合金成分的影响,为设计和发展Fe-Mn-Al-Cr系奥氏体无磁钢和低温钢提供一些参考。 根据Fe-Mn合金成分-结构关系,选择15—25wt-%Mn,0—1.50wt-%Al,0—0.40wt-%C
Abstract:The deformation a′-martensite in metastable Fe-Mn-Al-Cr alloys with the composition of 15—25wt-%Mn, 0-1.5wt-%Al, 0-0.4wt-%C and 0-1.2wt-%Cr has been studied by means of tensile tests at room temperature and -196℃. The following relationship between the quatity of deformation a′-martensite and the degree of deformation was confirmed: ln[a′/(1 -a′)]=lnA+Klnψ Statistical analysis shows that either lnA or K vary with the composition of alloys linearly at room temperature or-196℃.
