摘要：
The automotive use of magnesium is currently restricted to low-temperature structural components. Its use in elevated-temperature structural components such as transmission and engine parts requires the development of cost-effective alloys that can meet the elevated-temperature (150-175 degreesC) performance requirements of these components for strength and creep resistance. Rare-earth additions such as Ce Nd, Pr to Mg are known to improve the creep performance. An example of a rare-earth containing magnesium diecasting alloy with good creep resistance at 150 degreesC is the Mg-4Al-2 rare-earth alloy AE42. This paper discusses a new class of magnesium alloys containing alkaline earth elements such as Ca and Sr, which offers excellent creep performance.
