中文摘要	The critical points and time temperature transformation (TTT) curves of Fe-5%V-5%W-5%Mo-5%Cr-3%Nb-2%Co (Fe-V-W-Mo) were measured, and the effects of quenching temperature and cooling modes on the microstructure and performance of Fe-V-W-Mo alloy were investigated. The results showed that the hardness of Fe-V-W-Mo alloy increased until the quenching temperature reached 1025 degrees C and dropped down as the quenching temperature exceeded 1050 degrees C in oil cooling. The hardness obtained in air cooling and spray cooling exhibited a similar tendency as that in oil cooling, but the temperature at which the highest hardness was obtained in these slower cooling processes changed to a higher range. The hot hardness and toughness of Fe-V-W-Mo alloy increased with rising quenching temperature until it reached 1150 degrees C, and from then on the toughness began to drop. The main reasons why the structures and properties of Fe-V-W-Mo alloy obviously change under different quenching conditions are particularly analysed at last.
