Abstract

Abstract

Al-1%Si segments with 5 mm in diameter were held at different temperatures for 12 h and quenched. The recrystallization mechanism of the material was investigated by contrasting recrystallization texture after different-temperature heat treatment. An optimal heat-treated process was proposed, by which the original tissue with orbicular crystals of the material can be transformed into single crystals with high extended rate and electrical conductivity.
