| Popis: | A heat-resistant Ni-based alloy was formed by the heterophase laser powder metallurgy. The laser power was the main process parameter and was varied in the 250-750 W range. It was found that the microstructure of the alloy in the longitudinal section of the sample depended on the applied laser power. The structural analysis of the as-deposited materials revealed the presence of Ni3Al as the main strengthening phase along with carbide precipitates. |
