چکیده
Arbomex S.A. de C. V. is one of the largest worldwide manufacturers ductile cast iron camshafts, produced by means phenolic urethane no-bake sand mold casting method and cold box stack molding technology. As a result development high-strength ADIs, low alloyed with vanadium, for camshaft manufacturing, previous results were published on as-cast process austempering heat treatments applied to camshafts. In present work, camshafts 0.2 0.3 wt.% V, at temperatures 265 305 °C. The performance new was evaluated wear testing ensure function durability block-on-ring test valve train system evaluate volume loss material removed geometrical changes camshaft, respectively. ADIs treated °C showed microstructure constituted fine ausferrite that aided in obtaining highest resistance block-on ring test. No or pitting evidence detected lobes roller surfaces after OEM protocol during electric spin high conditions ADI V

Effects 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 ...

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 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...
