Hadfield steel%impact wear%mano-sized grains%amorphous structure
Under high energy impact contact loading, a turning on the weight loss－impact cycle (WL-N) curv e has been found, which results from the formation of nano-sized grains embedded in amorphous in the surface layersof Hadfield steel. As the impact energy increases, the wear rate, d WL/dN, first increases then decreases. The nanostructure due to the accumulation of plastic deformation is composed of nano-sized grains spanning 10 ～ 50 atoms and amorphous structures.
