Abstract It is found that the microcutting is the primary wear mechanism under low stress impact wear (3.5 J), while the delamination is of the primary one under high stress wear (about 160 J, which is similar to real one). The wear loss under high stress condition is also much more than low stress one. The wear mechanism of high stress wear is greatly affected by microstructures. The duplex of bainite and martensite has high wear resistance under high stress condition.
