Magnesium Die Cast Alloys for Elevated Temperature Applications

Abstract

<div class="htmlview paragraph">Mechanical testing and prototyping of several developmental magnesium die cast alloys have shown that certain magnesium alloys can be exposed to temperatures in excess of 232°C (450°F) and still have adequate strength. For example, one of the alloys tested at 260°C (500°F) had a tensile yield strength greater than 87 HPa (12.7 ksi). Further testing also revealed that some of these alloys possess better creep strength at 316°C (600°F) than AZ91D has at 177°C (350°F) with at least as good castability as AS41A.</div>
