主　　题：austenitic manganese steel mechanism of work-hardening 

摘      要：The effect of C,Mn and heat-treatment on work-hardening of austenitic Mn steel and the work-hardening mechanism have been investigated under non-severe impact loading *** results show that the ability of work-hardening in- creases with the increase of C and aging tempera- ture but decreases with *** work-hardening with high austenitic stability results mainly from dislocations,and that with low austenitic stability results mainly from combined effects of strain-in- duced martensite and high density of dislocations under non-severe impact loading *** wear resistance of medium manganese steel (Mn7) is 1.64-2.46 times that of Hadfield steel (Mnl3).
