w（B）约为 0 .0 7%时

合金的抗拉强度提高

伸长率明显提高

合金晶粒得到细化

Abstract

Influence of Al 5Ti

Al 5Ti B on the grain refinement and the tensile properties of ZL108 alloy with T6 state is studied. The results showed that high Si in Al Si alloy restrict the effects of Al 5Ti on the grain refinement of ZL108 alloy.0.20%～0.25% Ti content could improved properties of ZL108 alloy. The influence of Al 5Ti B on the properties of ZL108 alloy is better than those of Al 5Ti. Tensile strength and elongation is improved and α grain is refined for ZL108 alloy with 0.30%～0.35% Ti content and 0.06%～0.07% B content.
