Production of gradient structures in sintered TiC−(Ni,Mo) hard alloys on interaction with molten metals

Kinetic trends have been identified for mass transport of molten metals into sintered TiC?(Ni, Mo) hard alloys. Conditions have been identified for the mass transfer of the liquid by the migration and diffusion-migration mechanisms. Details are given of the formation of gradient structure in the TiC?(Ni, Mo) hard alloys on interaction with molten metals, where it is found that there are effects from the physicomechanical properties of the materials.
