Abstract

In situ Al₃Ti particle reinforced 2024Al alloy matrix composites (Al₃Ti/2024Al) were prepared by ultrasonic casting. Effects of in-situ Al₃Ti particle content on the microstructure, hardness, tensile performance and wear resistance of Al₃Ti/2024Al composites were investigated. The results indicate that with the increase of Al₃Ti content, grain in the composites prepared is refined gradually. When the Al₃Ti content is more than 12%, the density of the composites is decreased significantly. The hardness of the matrix and composites is increased with the increase of Al₃Ti content. The yield strength and tensile strength of Al₃Ti/2024Al with 8% Al₃Ti composites reach 357 MPa and 446 MPa, improved by 38.5% and 39.8% compared with those of as cast 2024Al alloy, respectively. The wear resistance of the composites prepared is increased with increasing in Al₃Ti content.
