High temperature oxidation of AZ91D magnesium alloy granule during in-situ melting

Oxidation behaviour of AZ91D was investigated by heating the alloygranules in a ceramic mould between 650 and 800 °C, for 30 and 60 min. The granules failed to melt in unprotected environment even when the temperature was increased to 800 °C. Raising the temperature increased the oxides thickness li...
