Synchrotron radiation diffraction study of structural changes in the interaction of liquid and solid metals

详细

Changes of the structure and phase composition occurring during the interaction of copper and its alloys in the solid-state phase with the liquid melts of indium, gallium and tin are considered. It is shown that the phase and morphological composition of interaction products depends on the relations between the rates of diffusion and the rates of reagent dissolution. Structural transformations that take place during contact melting and eutectic crystallization in the zones of indium–tin and indium–bismuth contacts are also considered. A hypothesis concerning the nature and microstructure of eutectics is proposed. All experiments are performed on the VEPP-3/VEPP-4 storage ring.
