摘要：
The combined effects of post-weld heat treatment (PWHT) and aging on the interfacial microstructure and tensile properties of alloy 800/2.25 Cr-1 Mo steel transverse weld specimens, welded using Inconel 182, were studied to determine the optimum PWHT temperature for the joint. In the present study, the joints were subjected to PWHT for 1 h at 948, 973, 998, and 1023 K, followed by aging at 873 K for 100-5000 h. The aging treatment at 873 K is intended to provide an accelerated simulation of service exposure at 773 K. The results of the present work show that the optimum PWHT temperature for the joint investigated is 973 K.
