摘　　要：对采用两类焊材的ＳＵＳ３０４与Ｇ１０２接头分别进行了不同加热规范的模拟加热试验，并将接头局部进行了化学成分、金相组织与显微硬度测定。结合接头中的应力分析。A simulated heating experiment is made at different temperatures for the joints of SUS304 and G102 welded with two kinds of different deposited metal respectively. and the composition, microstructure and microhardness of partial sections of these joints are determined. The early rupture mechanism of these dissimilar metal joints in power boilers is studied through the result of the test and the stress analysis in the joints.
