含碳量达到2.3%后，基体以马氏体为主，耐磨性比低碳的高钒高速钢大幅提高。
After the carbon content reached 2.3%, the matrix is martensite primarily and the impact wear resistance performance enhanced largely compared with the low-carbon high vanadium high-speed steel.
VC较高的形态及较高的硬度是高钒高速钢具有比高铬铸铁较好的耐磨性的主要原因。
It is the main reason of higher form and hardness of VC for high vanadium high speed steel with better wear resistance than that of high chromium cast iron.
高钒高速钢干滑动磨损机理为显微切削和疲劳磨损的复合，并且有应力作用下碳化物的碎裂及脱落。
The wear mechanism of high vanadium high-speed steel is combined micro-cutting and fatigue wear with carbide particle breaking and peeling off under stress.
