Abstract: The present invention relates to creep-resistant magnesium-based alloys with low susceptibility to hot tearing, and with improved ductility, impact strength and fracture toughness, and corrosion resistance. The alloys contain at least 96 wt % magnesium, 1.5 to 1.9 wt % neodymium, 0.10 to 0.30 wt % yttrium, 0.35 to 0.70 wt % zirconium, 0.05 to 0.35 wt % zinc, 0.01 to 0.10 wt % calcium, 0.01 to 0.15 wt % strontium, and 0.0000 to 0.0005 wt % beryllium, and they are suitable for low pressure and gravity castings. Articles, that are castings of the alloys, are suitable for applications at temperatures as high as 175-250° C.

Abstract: Magnesium-based alloys are provided which exhibit improved resistance to creeping and to corrosion, as well as improved strength, and good castability. The alloys are suitable for applications at both ambient and elevated temperatures.
