Evaluation of High Temperature, Cast Magnesium Alloy, Front Engine Covers

摘要

A variety of new magnesium casting alloys specifically designed for high temperature applications are now available. However, there is little published data from component or from test specimens sectioned from component castings. In this study, the mechanical properties (tensile, bracket thread integrity, bracket distortion, fastener/attachment point acceptability, resonance and shaker fatigue durability) of front engine covers made from three magnesium alloys (AZ91D, AJ62x and MRI-153M) and from aluminum alloy 380 are presented.
