40CrNiMo钢的冲击磨损实验发现，表面白层中产生了硬度更高的绝热剪切带.这种绝热剪切带有非常细小的晶粒，比白层更容易产生裂纹或断裂本文的研究认为：冲击磨损的白层中发生了动态回复，而白层中的绝热剪切带则可能发生了动态再结晶
Adiabatic shear band was observed in surface white-etching layer in impact wear test.The band possesses very fine crystalline grains,and is harder than white-etching layer.The adiabatic shear bnad in white-etching layer is liable to fracture or cracking in impact wear.It's supposed that dynamic recrystallization occures in the band in white-etching layer whereas dynamic recovery takes place in the white-etching layer.
