| Краткий осмотр (реферат): | Mo₂FeB₂ based cermets with various Ni, Cr and C concentrations were prepared. The effect of Ni, Cr and C on the phase composition and microstructure was investigated by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDS) and X-ray diffraction (XRD). Hardness (HRA) and fracture toughness (K1c) were also measured. It was found that nickel alloying leads to formation of two-phase state represented by Mo₂FeB₂ boride and austenite. Chromium alloying results in austenite to ferrite transformation and M₂₃C₆ and M₆C carbide precipitation in the case of carbon doping. Also, it was found that chromium influences the borides mean size |
