The paper considers manufacturing of metal matrix composites (MMC) by means of selective laser melting. The heat-resistant nickel-based Ni–Cr–Mo–Nb–Al alloy was chosen as a matrix material, the Y2O3 oxide was chosen as a strengthener. After mechanical alloying the obtained powder was used in SLM for the production of a material. The synthesized material’s condition was examined after the SLM process and after hot isostatic pressing (HIP). In the structure the areas containing Y, Al and O-based compounds were found. The creep-rupture tests of samples after HIP and heat treatment were performed and the results were explained by fractographic analysis. |
