Abstract

Abstract

A new spring steel 55SiCrV smelted in the laboratory was used as the raw material i n this paper to investigate the effects of rolling deformation temperature and cooling speed on the mechanical properties and microstructure of 55SiCrV by means of CCT curve drawing, thermal simulation test and metallographic structure observation, and the reasonable parameters of rolling and cooling process were determined. The CCT curve of 55SiCrV shows that the critical cooling rate of martensite formation is about 3 ℃/s, and the temperature of martensite formation is about 245 ℃. The rolling deformation temperature of 55SiCrV should not be higher than 900 ℃ and the cooling rate should be lower than 5 ℃/s in the actual rolling process, which can avoid the formation of martensite in the microstructure and significantly deteriorate the fatigue performance, while ensuring the best combination of strength and toughness.
