SFs gas that is used as a protective cover gas for Mg and Mg alloys during melting and casting has extremely high greenhouse effect. CaO added Mg alloys could maintain their original mechanical properties and original abilities such as flu id ity and hot tearing susceptibility. The ignition temperature increased w ith increasing CaO addition under ambient atmosphere and nitrogen atmosphere. liie minimum amount o f SF6 gas decreased by 0.13 wt%CaO added AZ91D Mg alloy in the sealed condition.
