Abstract
The microscopic failure modes of high pressure die cast (hpdc) AZ91HP magnesium alloy is identified by means of in situ tensile analysis. The study aims at: (i) explaining the consequence of different micro-inhomogeneities on failure and, (ii) confirming to which extent shrinkage porosity influences failure. Microstructural analysis at different deformation stages verify interaction of pores, Mg17Al12 (β) particles and inclusions during failure and indicates predominant intergranular brittle failure of the material.
