Influence of Carbides and Strain-induced Martensite on Wear Resistance of Austenitic Medium Manganese Steels

The abrasive wear behaviour of austeniticmedium manganese steels was studied under weakcorrosion-abrasive wear simulating the linerplate in wet metallic ore bail mill undernon-severe impact-loading working condition.Results show that the work-hardening mechanismand the wear resistance of high carbon austeniticmedium manganese steels differ from those ofmedium carbon austenitic medium manganese steel.Under non-severe impact and weakcorrosion-abrasive wear,the wear resistancesof high carbon and medium carbon austeniticmedium manganese steels are 50-90% and 20-40%higher than that of Hadfield steel respectively.
