| Abstract: | According to the character and the principle of fatigue fracture,heat treatment experiment tests with different parameters are carried out for the cold rolling mandrel made of steel W6Mo5Cr4V2.The results show that middle temperature quenching plus several times of high temperature tempering improves markedly the microstructure of steel W6Mo5Cr4V2 markedly with better strength-toughness combination achieved.Thus the performance of anti-fatigue and fracture is refined. |
