performance. While conventional ductile iron grades have long been used successfully for automobile components, the high strength and toughness of austempered ductile iron offers much greater potential for weight reduced designs (Warrick et al, 2000). It is
ductile iron, which was austempered using different parameters of heat treatment. The specimens were first solution treated 1 hour in 910 o C and then isothermally quenched for different time in silicon oil bath of temperature 275, 325, 300 and 350 o C.
Production of a conventional spare gear from austempered ductile iron was aimed and concluded at a later stage. The same casting and treating conditions attributed to the optimum structure properties were used for production of the gear. and 350℃ for time intervals of 60, 120, 240 minutes.
26/9/2014· Cast iron family represented by grey cast iron, ductile cast iron and austempered ductile iron (ADI) is used in experiments as a case presenting considerable variations in microstructure. Modal testing was performed on specimens made of the selected materials in order to extract the corresponding modal parameters.
Austempered ductile iron has emerged as a notable material in several engineering fields, including marine appliions. The initial austenite carbon content after austenization transform but before austempering process for generating bainite matrix proved critical in controlling the resulted microstructure and thus mechanical properties. In this paper, support vector regression is employed in
