Abstract
Under high energy impact contact loading, a turning on the weight loss-impa ct cycle (W-L-N) curve has been found, which results from the formation of nano-sized grains embedded in amorphous in the surface layers of Hadfield s teel. As the impact energy increases, the wear rate, dW(L)/dN, first increa ses then decreases. The nanostructure due to the accumulation of plastic de formation is composed of nano-sized grains spanning 10 similar to 50 atoms and amorphous structures.
