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