Study on the Mechanical Properties of Single Crystal Aluminum by Ohno Continuous Casting

Abstract:

In this paper, tensile properties at room temperature and bending rupture properties of single crystal aluminum wire, 4mm in diameter, fabricated by ohno continuous casting were studied, and its fracture was analyzed. The results showed that: Compared with polycrystalline aluminum samples, the yield strength of Ohno Continuous Casting single crystal aluminum changed little; Ultimate strength decreased by 42.7%; Elongation and reduction of area increased by 111.5% and 575%; Bending fatigue strength have been enhanced distinctly. Fracture of single crystal aluminum were flat tip shape, the slip line near fracture parallel to each other and uniformly distributed, the fracture is typical dimple structure and the dimple size were relatively uniform, appeared as parabolic.
