Interfaces between Lead and Amorphous Matrices in Immiscible Alloy Systems

摘要

Interfaces between solid lead and amorphous matrix are described, with experimental data from system of lead particles embedded into Al-Cu-V amorphous matrix. Since the structure of the amorphous matrix cannot be described with surety, it has been approached by taking known factors in account, such as the relative stability of various facets of lead and its interfaces with quasicrystals. Lead particles take a round shape in accordance with the amorphous matrix, and are often twinned to form more uniform facets (with uniform energy) on the surface/interface. Interface stability of the lead particles is indicated by their melting and solidification behavior. Therefore melting and solidification behavior of the embedded particles in amorphous matrix has been compared with those in crystalline and quasicrystalline matrices.
