The Effect of Mechanical Properties of 2.0% Vanadium Ductile Iron after Double Quenching Method

Abstract:

This study presents the effect of hardness and impact of 2.0% vanadium ductile iron after double quenching heat treatment method on different temperature. Addition of 2.0% Vanadium to ductile iron was produced through conventional CO2 sand casting method. The specimens were preheated to 500°C for 30 minutes, then oil quenched and austenitized at 900°C for 60 minutes before oil quenched again. After that, the specimens were tempered for 90 minutes at three different temperatures including (i) 500°C, (ii) 600°C, and (iii) 700°C respectively before cooled to room temperature by nature air. It is evident found that the addition of 2% Vanadium contributed to the slightly improved to the tensile strength properties but better hardness and impact compared to conventional ductile iron. The higher hardness and impact were found at 500°C and 600°C tempering temperature respectively.
