Near-Net-Shape Manufacturing of Austempered Ductile Iron (ADI) Components
Near Net Shape (NNS) manufacturing produces the engineering components closer to its final specification in single stage or minimum number of stages. ADI process technology is one of the NNS manufacturing technologies, currently being followed by the industries for manufacturing of engineering components at competitive price. Austempered Ductile Iron is a new class of engineering material which...
متن کاملEffects of Carbides on Fatigue Characteristics of Austempered Ductile Iron
Crack initiation and growth behaviour of an austempered ductile iron (ADI) austenitised at 800C and austempered at 260C has been assessed under three point bend fatigue conditions. Initiation sites have been identified as carbides remaining from the as cast ductile iron due to insufficient austenisation. The number of carbides cracking on loading to stresses greater than 275 MPa is critical in ...
متن کاملDevelopment of High Silicon Dual Phase Austempered Ductile Iron
This work deals with the feasibility of obtaining Austempered Ductile Iron with Dual Phase structures (DPADI) through heat treatment, starting from different as-cast microstructures. The mechanical properties on these microstructures were evaluated. DPADI microstructures were obtained by adding different tenors of silicon (2.4% to 4.2%) to the melts and keeping the other alloying elements const...
متن کاملThe Bainite Reaction Kinetics in Austempered Ductile Iron
Bainitic reaction kinetics in ductile iron contained according to Ukrainian standard (weight %) 3.603.80 carbon, 2.60-2.80 Si, 0.12 Mn, 0.60 Cu and additionally alloyed by Mo (0.15-0.20) has been studied. It was found that the overall transformation kinetics becomes slower as transformation temperature increase. This is because more intensive redistribution of carbon into austenite at higher te...
متن کاملOptimizing the Microstructure and Mechanical Properties of Austempered Ductile Iron for Automobile Differential Gear
Austempered ductile iron (ADI) has been proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness combined with good wear resistance and machinability. These properties can be achieved upon adequate heat treatment which yields the optimum microstructure for a given chemical composition. The heat treating of the ductile cast iron produces th...
