By optical and scanning electron microscopy and quantitative X-ray diffraction and X-ray analysis revealed that the increase in the rate of cooling during crystallization from the melt leads to a reduction in the size of the phase components of the alloy of 20 wt.% WC-80 wt.% W2C, increased compressive stress in the matrix phase W2C and stretching inclusions in the WC, which leads to an increase in the hardness of 1.5 times and 2-4 times the strength of relit, that is used on an industrial scale for the strengthening of machine parts and mechanisms operating in abrasive wear and high contact loads.
