The Microstructure Comparison between Rapid Solidification AlSi Alloys and Conventional Casting AlSi Alloys
Due to the rapid solidification process,the materials offer many advantages, such as homogeneous composition,refining microstructure,no macrosegregation and low oxygen content.Compared to conventional casting,forging and powder metallurgy process, rapid solidification technology could produce the alloys not to be realized by casting with short production routes,simplified processes and high deposition efficiency.
♦ High density metal materials have better strength.
♦ It can be seen from the microstructure in the left figure that the traditional casting process AlSi alloy is dendritic. The silicon phase of AlSi alloy with rapid cooling by Zuoyuan is equiaaxial, and the grain distribution is uniform, which greatly improves the comprehensive performance of the material.
