| Abstract: | The technological parameter of post-welded heat-treatment is determined by welding thermal simulation test. The behavior of carbon migration of the joints with 9%Cr and 5% Cr weld metal was investigated respectively, and the carbon concentration, carbide type and distribution in carbon-depleted layer as their effect on the enduring strength of the joint were analyzed. |
