C/V graphite cast iron containing a small amount of Cu and Mo for better hardenability and microstructure, was poured into the CO₂mold and then austenitized at 900℃ for 2hours. After austenitizing, the specimens of castings were austempered at 250℃, 300℃ and 350℃, respectively. The interrelationship among matrix structures, mechanical properties, wear characteristics, and austempering temperatures were investigated in this study. Wear amount increased with the increase of ferrite and retained austenite. The amount of sliding wear loss increased as sliding speed and final load increased, and wear loss of austempered C/V graphite cast iron under dry sliding condition was characterized by three models; initial wear, stationary wear and abnormal wear. The wear amount decreased with the decrease of austempering temperature, with the increase of tensile strength and hardness.
