Abstract
The paper presents the study of the structure of the deposited metal Fe0.09C31Cr8NiN2Mo at different cooling rates. The research was carried out using the EBSD analysis method in the initial state after surfacing. The effect of post weld heat treatment on the resulting percentage of γ/σ phases in the deposited metal, depending on the percentage of γ/σ phases in the before heat treatment state is considered. The ways of improving the performance characteristics of the metal deposited with materials such as Fe0.09C31Cr8NiN2Mo to a temperature of 350–400°C are proposed.
