摘要
In this paper, comprehensive property crack resistance, work hardening and abrasion resistance of a series of double phases austenitic alloys(FAW) has been studied by means of SEM, TEM and type MD 10 impacting wear test machine. FAW alloys are of middle chromium and low manganese, including Fe Cr Mo C alloy,Fe Cr Mn C alloy and Fe Cr Mn Ni C alloy, that are designed for working in condition of impacting abrasion resistance hardfacing.Study results show that the work hardening mechanism of FAW alloys are mainly deformation high dislocation density and dynamic carbide aging, the form of wearing is plastic chisel cutting. Adjusting the amount of carbon, nickel, manganese and other elements in austenitic phase area, the FAW alloy could fit different engineering conditions of high impacting, high temperature and so on.
