中文摘要	Influences of tempering temperature, holding time and tempering times on the microstructure and performance of Fe-5%V-5%W-5%Mo5%Cr-3%Nb-2%Co(Fe-V-W-Mo) were investigated by means of metallography, optical microscopy, hardness measurements, impact tester and pin abrasion tester. The results show that the hardness of Fe-V-W-Mo alloy remains constant when tempered below 350 degrees C. The hardness decreases gradually as the tempering temperature increase until around 475 degrees C and then it increases again to a peak at 525 degrees C. The hardness of Fe-V-W-Mo alloy reaches nearly the highest value after the first tempering and decreases after triple-tempering. The toughness of Fe-V-W-Mo alloy increases until the tempering temperature reaches 475 degrees C and then decreases until the temperature reaches 525 degrees C. However, it increases again when tempering is beyond that temperature. The excellent wear resistance can be obtained by tempering at 500-550 degrees C.
