摘要: 将CLAM钢采用真空扩散连接工艺进行连接后,观察分析采用不同连接温度和保温时间连接的接头微观组织,通过拉剪试验对接头的剪切强度进行评测。结果表明:在合适的连接温度和保温时间下用真空扩散连接的方法可以实现CLAM钢的可靠连接(结合率大于90%),接头剪切强度可达648 MPa。

Abstract: In this study, CLAM steel was welded by vacuum diffusion bonding. The microstructures of the joints bonded under different temperatures and holding times were investigated. The mechanical properties of the joints were characterized by shear strength tests. The results indicate that the vacuum diffusion bonding can realize the reliable joining of CLAM under the appropriate bonding temperature and holding time（bonding ratio not less than 90%）. The shear strength of joints may be as high as 648 MPa.
