Analysis of wear track and debris of stir cast LM13/Zr composite at elevated temperatures

► Good interfacial bonding between zircon sand particles and Al matrix was observed. ► The effect of temperature on the wear behavior of LM13/Zr composites was studied. ► Wear resistance of the composite was improved with addition of zircon sand. ► Transition temperature from mild to severe wear also improved in composite. ► SEM analysis of the tracks and debris was done to establish wear mechanism.
