摘要：This study reported the researches done so far on cast irons and that of its wear resistant candidate (cast iron) and the need to improve on the impact toughness of this wear resistant candidate. Carbidic Austempered Ductile Iron (CADI) has gained tremendous recognition in Agricultural sector because of its good wear resistance, which makes it a useful material for wear application. It has been used for ploughshare part production, cultivator, bucket conveyor, crusher plates since its production some few years ago. A review on the researches on carbidic austempered ductile iron (CADI) as an offspring of austempered ductile iron (ADI) of cast iron family showed its relevance in the production of soil opener (tiller, cultivator, ploughshare, crusher plates) is principally due to its good wear resistance properties with relatively fair impact toughness. The CADI is a novel type of austempered ductile iron consisting carbides in the ausferritic matrix. This is produced by austempering carbidic ductile iron at different temperatures and times. The CADI is a viable replacement for forged steel and has been used vastly in mining, automobile and agricultural machinery sectors. Meanwhile, its relatively low toughness, caused by coarse carbides in the matrix of the cast iron, has a destructive influence on the abrasion resistance of CADI and so limits its applications. Producing cast iron with a good balance of abrasion resistance and toughness through micro-structure modification is a welcome idea for the development of ploughshare parts for agricultural application.
