The paper examines how additions of 5, 10, and 20 wt.% molybdenum influence the structure, stress–strain state, phase composition, and size of phase components in WC–W2C alloys. It is found that 5 wt.% molybdenum leads to 30% increase in the microhardness and twofold to threefold increase in the wear resistance of cast tungsten carbide compared to the alloy without additions. Higher molybdenum content of the WC–W2C alloys changes the phase composition and increases compressive stresses in the W2C matrix phase and tensile stresses in WC, (Mo, W)2C, and Mo2C inclusions.
