| Abstract: | The Sn-10%Sb alloy can happen from 856 ℃ to 960 ℃ temperature-induced liquid-liquid structure transition.The effect of temperature-induced liquid-liquid structure transition on the solidification behavior and microstructure of Sn-10% Sb alloy was studied. The results show that the required supercooling degree increases and the solidification microstructure is refined obviously after the structural transformation of the alloy melting. |
