Abstract:	摘要： Al–Si alloys, with excellent properties such as low weight, low thermal expansion coefficient, and high wear-resistance, are ideal materials for the automobile and aerospace industries. However, their applications have been hampered by the coarsening of the primary-Si particles in Al–Si alloys. In this study, the rolling-and-T6-treatments effect on A6061/Al 2 O 3 metal-matrix composites is investigated. The A6061/Al 2 O 3 metal-matrix composites with different amounts of reinforcing Al 2 O 3 particles are examined in the aspects of wear resistance and hardness. Upon the T6 treatment, the hardness is enhanced in all cases and is summarized. The results suggest that the increase of Al 2 O 3 particles reduce the wear rate. The possible reinforce mechanisms and the environmental temperature effects are discussed. This improvement in wear resistance is due to the particle size refinement of silicon at a high percentage-roll-reduction. 出版日期： 2016-02 出處： Proceedings of the Institution of Mechanical Engineers.
