摘要

Features of structure and phase formation in Cr - Cu -Ni(Co, Fe) systems during liquid-phase sintering in a vacuum of (2-4) X 10~(-3) Pa at 1200 and 1270 deg C are studied. It is shown that with introduction of elements of the iron family into molten copper there is dispersion of refractoty particles and formation at the boundary with the readily melting component of a transition layer whose structure and componsiton are determined by the nature of the addition. Growth of refractory particles during liquid sintering of composites of the system Cr - Cu - Ni is controlled by diffusion of elements intc solid phase of the transition layer.
