Strain Hardening Behavior of Fe-Mn-Al-C Low Density Steels During Tensile Deformation

摘要：

　　The strain hardening behavior was investigated during tensile deformation of Fe-26Mn-xAl-1C steels with different Al concentrations in the present work.It was revealed that the variation in Al concentration could make a marked influence on the stacking fault energy of the materials and the yield strength increases remarkably in Fe-26Mn-xAl-1C steels with Al changing from 8 to 11(wt%).Different analysis such as Hollomon analysis,C-J analysis and modified C-J analysis have been adopted to investigate the strain hardening behavior of different steels.It is indicated that C-J analysis and modified C-J analysis can describe the strain hardening of low density Fe-Mn-Al-C steels fairly well.The present work can provide some useful data for alloy design and applications of low density Fe-Mn-Al-C steels in automobile industry.
