Investigation on the Property of High Si-Al Alloy Prepared with Ultrasonic Vibration Aided Casting Technology

Abstract:

In common hypereutectic high Si-Al alloy, the properties and applications of high Si-Al alloy was influenced by the thick multi-triangle shaped primary silicon seriously. In this paper, the fine hypereutectic Al-Si alloy was fabricated with ultrasonic vibration aided casting technology and the influence of ultrasonic vibration on the alloy structure is investigated as well as the influence of the silicon content on the wear volume and hardness with the comparison of microscopic structures. The results show that the increase of silicon content ascends the hardness of the high Si-Al alloy. However, along with increase of silicon content, the wear loss decreases initially and increases when the silicon content is larger than 22%.
