Abstract

The influence of RE modification on the structure and properties of Al-Si alloy was investigated. The optimun range of RE addition and the modification temperature were obtained. After heat treatment

the ultinate strength of Al-Si alloy could exceed 350 MPa

and the elongation could equel to 2%.
