Heat-resistant magnesium alloy member

摘要

A heat-resistant magnesium alloy member having specially excellent molding property and elongation while keeping creep resistance property, which comprises 2 to 6% by weight of aluminum and 0.5 to 4% by weight of calcium, and the balance comprising magnesium and inevitable impurities, having a Ca/Al ratio of no more than 0.8, preferably no more than 0.6. The method of preparing the heat-resistant magnesium alloy member is characterized in a semi-solid injection molding at a range between a solidus temperaaature of the alloy and a liquidus temperature of the alloy.
