Abstract
In this study, the heat-treating was done from 923 to 1523K for 2s to 24h. In heat-treating the weld metal with δ ferrite above 2%, the absorbed energy decreased with increasing amount of prior δ ferrite. In the case of treatment at 923K, degradation of absorbed energy was observed. On the other hand, the absorbed energy of fully austenitic weld metal was constant independent of heat-treating time and temperature. In the type 316L weld metal reported previously, the absorbed energy tended to rise slightly by heat-treatment for up to 120s. In Type 308L weld metal, such a tendency was not observed. This is attributed to good coherency of the δ/γ interface compared to Type 316L eutectic δ ferrite weld metal. The decomposition of δ ferrite was slower than that in Type 316L.
