Abstract

Abstract

An Al-1%Si bar with 8 mm in diameter and single crystal was made with self-made vacuum vertical continuous unidirectional casting equipment. The microstructure evolution and stability during continuous unidirectional solidification were studied. The Si distribution of particles in Al matrix was analyzed and a method was proposed that can make Si diffuse in Al homogeneously.
