Microstructure of Casting and Solid Solution of Cu-7.5Ni-5.0Sn Alloy

The casting and solution microstructure of Cu-7.5Ni-5.0Sn alloy were studied.The results showed that the cast Cu-7.5Ni-5.0Sn alloy existed serious dendritic. The microstructure of the cast Cu-7.5Ni-5.0Sn alloy is divided into three parts, namely, gray dendritic (α phase, ie, Cu-Ni solid solution), interdendritic white bright objects or bone-like organization ((CuX、Ni1-X)3Sn phase, ie, γ phase), dark gray organization of the transition between the dendrite and the bone-like organization (α phase and γ phase mixture). Solution temperature will affect the solid solution effects. The best solution condition is heated at 800°C for 1h. Subsequently, the alloy cold rolling deformation is up to 50%.
