The mechanical properties of high pressure die cast (HPDC) magnesium can be highly variable and dependent on the manufacturing process history and on location within a casting. This investigation is providing experimental input to modeling activities for the development of an ICME capability, to assess and quantify the impact of section thickness on the microstructure and tensile behavior of HPDC Mg AM50 alloy. AM50 2.5 thick plates were super vacuum die cast and characterized via quantitative metallography and uniaxial tensile testing. Plates were processed by hot isostatic pressing (HIP) to identify the effect of different microstructural features, specifically β-Mg17Al12 and shrinkage porosity, on the mechanical behavior. This allows investigation specifically on the effects of casting defects, such as oxide bifilms on the microstructure and tensile behavior of these plates.
