Abstract

The article presents the results of research and development on basic technological synthesis parameters of Mo–Si–B system metal composite material (MCM) by EBM and SLS methods. Additionally, the paper provides the investigation of the mechanisms of interface formation and diffusion processes at the interface «matrix–strengthening agent» in the process of synthesis of blanks by EBM and SLS. The powders have been analyzed by scanning electron microscope imaging, the images from which show that the powder granules have a splinter shape.
