The wear resistance was evaluated using a wear tester, it was noted that the wear resistance values of the CADI ranged from 2.35E8 cm-2 to 3.74E9 cm-2. ![]() Microstructural characterization was then carried out. ![]() The produced carbidic ductile irons (CDI) were heated to austenitic temperature of 910oC and held for 1 hour, then austempered at temperature of 325oC and held at different times (1-3 hours) to obtain carbidic austempered irons. Six alloys with a carbon equivalent value of 4.44 (hyper-eutectic composition) were used to evaluate the produced CADI, with antimony content ranging from 0.096 to 0.48 wt. ![]() This work investigated the effect of antimony on the impact toughness and wear resistance of carbidic austempered ductile iron (CADI).
