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...
