Study of an Al-Ca Alloy with Low Young's Modulus

摘要

Aluminum alloys with low Young's Modulus have not been well studied. This study offers properties and production methods of an Al-Ca alloy. Here, an Al-Ca alloy with a small amount of Fe addition was prepared by Direct-Chill (DC) casting, extrusion and rolling, microstructure and mechanical properties were investigated after every process. Low Young's Modulus of less than 55 GPa and increased yield strength was achieved when adding heat treatment after extrusion and rolling.
