摘　　要：本文研究了CLAM钢扩散连接接头在600℃以及700℃进行短时间（50~100 h）时效后的显微组织变化规律。结果表明,时效过程并不会改变接头附近马氏体板条的取向,接头界面两侧的马氏体板条取向始终保持一致。随着时效温度的升高,接头附近的碳化物含量水平有所提高,时效时间的延长也会促进碳化物的析出。In this peper,change rule on microtructure of diffusion bonding joint for CLAM steel after sging for short time（ 50 ~ 100 h） at 600 ℃ and 700 ℃. The result shows that the aging process does not change the oritation near martensite plate and the oritation of martensite plate on either side of the joint interface stays the same. Carbide content near joint have improved with increasing aging time,and precipitation of carbide is promoted as extending aging time too.
