Improvement of Hot Tearing Resistance of AZ91 Alloy with the Addition of Trace Ca [PDF]

Materials (Basel), 2023
Hot tearing is the most common and serious casting defect that restricts the light weight and integration of magnesium alloy components. In the present study, trace Ca (0–1.0 wt.%) was added to improve the resistance of AZ91 alloy to hot tearing. The hot
