High manganese steel, more commonly referred to as Hadfield steel, is an austenitic manganese steel that exhibits high toughness and wear resistance after work hardening. However, in extremely high wear applications, the wear rate can be so high that the alloy never reaches peak hardness. One proposed method to increase the wear life and take full advantage of the work hardening is to ultilise carbides within the matrix. The negative influence of carbides on toughness is a concern as Hadfield steels are normally used in high impact applications. A balance is therefore required between increasing the wear resistance and maintaining an adequate toughness for the required application. This research focuses on Fe–12.1wt.%Mn–1.2wt.%C alloys with Nb containing carbides formed in-situ. The mechanical properties including toughness and wear resistance are compared to standard Hadfield steel. Microstructural characterisation is also performed before and after failure to assess the failure mechanisms.
