Creep Resistant Magnesium Diecasting Alloys Based on Alkaline Earth Elements

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