The Production of thin wall austempered ductile iron components can have strength-to-density ratios that approach those of cast aluminum, making it theoretically possible to apply austempered ductile iron in high strength light weight parts. Short term austempering treatment process was used to obtain thin wall austempered ductile iron castings. The samples of 2 and 3 mm thickness were austenitized at 900°C for 30 minutes followed by holding at 350°C, 400°C and 450°C inoculated by Ce-Ca-Al-S-O-FeSi at 0.4% for 2, 5 and 10 minutes for each temperature. The austempered samples are comparatively harder than the as-cast ductile iron plates. The hardness also decreases with increase in austempering temperature for a given austempering time for thinner plates and for a thicker plates the hardness is more for the samples treated at 400°C than those treated at 350°C and 450°C for a given austempering time. The Yield strength and the ultimate tensile strength decreased for as-cast ductile iron and increased for thin wall austempered ductile iron samples with increase in plate thickness inoculated by Ce-Ca-Al-S-O-FeSi compare to Zr-Mn-Ca-Al-Ba-FeSi and Sr-Al-Ca-FeSi at 0.4%. © 2017 Elsevier Ltd.
