Abstract

In this paper, the size distribution and quantity of carbides precipitated during the partition process of 60Si2CrVA spring steel treated by Q&P with different partition time were statistically analyzed by SEM. Carbide particles were obtained by electrolytic extraction of 60Si2CrVA treated by Q&P with partition time of 1200s, and the contribution of different kinds of carbides to the yield strength was calculated. The results show: during the partition process of 60Si2CrVA spring steel, the size and volume fraction of carbides increase continuously with the extension of partition time, while the contribution of carbides to yield strength decreases gradually. Carbides rich in V( 80nm)and carbides rich in Cr(>80nm)are mainly precipitated in the partition process, and carbides rich in V play the key role in precipitation strengthening.
