Formation and control of fluorescent linear defects in Mg-RE alloy casings

Key Points

• Fluorescent linear defects in Mg-RE alloy casings were successfully characterized and controlled.
• The maximum linear defect density reached 5.3 defects per meter in specific conditions.
• Assessment using casting methods examined the effects of heat treatment on defect formation and microstructure.
• This insight may lead to improved casting processes and fewer defects in future alloy applications.
