High performance creep resistant magnesium alloy

摘要

The invention provides a magnesium based alloy consisting of at least 94.8% magnesium, 2.5-4.6% neodymium, 0.05-0.40% yttrium, and 0.03-0.65% zirconium, exhibiting good castability, high strength, high corrosion resistance and high creep resistance even at high temperatures. The alloy is suitable for high pressure die casting, sand casting, investment casting, permanent mold casting, twin roll casting, or direct chill casting.
