Abstract
It has been shown that the contact melting rate for metals is determined by the fact that at least one of them has a quasi-liquid layer on the surface. As a result, the diffusion of metal atoms occurs in the liquid phase, and not in the solid phase, which determines the characteristic contact melting time (seconds and minutes).
Highlights
The processes underlying the appearance and growth of the intermediate phases that occur during the alloying of various metals to obtain intermetallic compounds and heterogeneous mixtures have not yet been fully studied
Of particular theoretical and practical interest is the clarification of the conditions required for mass transfer to occur at the boundaries of coexisting phases
Contact melting is a phenomenon in which two metals that are initially in a solid state begin to melt upon contact
Summary
The processes underlying the appearance and growth of the intermediate phases that occur during the alloying of various metals to obtain intermetallic compounds and heterogeneous mixtures have not yet been fully studied. The reason for this melting is that metal atoms diffuse into each other; as a result, the melting temperature of such a solution decreases. In order for metal atoms ory of Quasi-Liquid Layer.
