摘要: Abstract There are two important nucleation problems in solid state amorphization. One is to understand how an amorphous phase forms at interface between crystalline elements; the other explain of a compound advancing alloy and element suppressed until layer has attained temperature- system-dependent critical thickness. This article discusses both issues. It also examines relationship transient competitive growth models for suppression thin-film diffusion couples. A transient-nucleation model used represent information about transition from growing intermetallic on kinds map: one thickness against temperature, temperature anneal time. The discussion concentrates upon most-studied amorphizing system, Ni-Zr, though points made may be relevant interpreting s...
