Structure and Property Stability of Rapidly Solidified In-Sn γ-Phase Alloy

Article Preview

Abstract:

The crystallization characteristics of the binary alloys which have InSn4 intermetallic compounds(IMC) were investigated.The influence which high undercooling had caused to the process of lattice formation,the lattice evolution in the later period of solidification,the stabilization process of the alloy property were mainly studied.The results show that the solute redistribution is restrained intensely in the rapidly solidified condition,the components of InSn4 IMC distribute uniformly,the highly undercooling structure have small sub-grain structure.X-ray diffraction analysis show that strong (0001) texture is formed in the alloys,EBSD analysis show that many sub-boundaries exist in the grains.While these unstable structures have an isothermal annealing between 20~140oC,the texure feature of the alloys weaken,and at the same time the microhardness lower in varying degrees.
