Abstract—

Mo5SiB2-based ceramics were fabricated from elemental powders by forced SHS compaction and hot pressing of SHS-produced powders and specific features of product patterning were characterized by XRD, time-resolved XRD, SEM/EDS, and TEM/EDS. Best results were obtained upon hot pressing of SHS-produced Mo–Si–B powders: resultant material was single-phased Mo5SiB2 with a mean grain size of 2–10 μm.
