Study on Interface Pattern of Zn-5wt%Al Alloy during Unidirectionally Solidification

Abstract:

The interface pattern of Zn-5wt%Al alloy was investigated during unidirectionally solidification with different withdrawal rate and superheat degree. It was showed that the pattern of liquid/solid interface varied with withdrawal rate and superheat degree. While the superheat degree of alloy melt was low and the withdrawal rate was increased, the change of interface pattern was the same as the normal change of interface pattern. While the superheat degree of alloy melt was high and the withdrawal rate was increased too, the change of interface pattern was different. As a result, the pattern and stability of liquid/solid interface was chosen by withdrawal rate and superheat degree mainly.
