Improvement of Abrasion Wear Resistance of Ductile Iron by Two-Step Austempering
Advanced Materials Research, 2012 Abrasion wear rates of conventional and two-step austempered ductile cast iron (ADI) were investigated. Conventional austempering and two-step austempering processes were carried out at 280, 300, and 320°C. Microstructures revealed that higher austemperig temperature resulted in coarser ausferrite and higher volume fractions of blocky retained ...

Materials and Manufacturing Processes, 2003 Abstract An investigation was carried out to examine the influence of microstructure on the stress corrosion cracking (SCC) growth behavior of an austempered high-carbon (1.00%), high-silicon (3.00%), and high-manganese (2.00%) cast steel. Compact tension specimens were prepared from this cast steel as per American Society for Testing Materials ...

Study of wear behaviour of ductile iron subjected to two step austempering
International Journal of Materials Research, 2010 Abstract An investigation was carried out to examine the influence of two step austempering on microstructural parameters and the wear behaviour of austempered ductile iron. Ductile iron was austenitised at 900°C for 30 min, and then austempered successively at two different temperatures.

Materials Science Forum, 2012 In this investigation a new low carbon and low alloy (LCLA) (Third generation AHSS) steel with exceptional combination of yield strength and fracture toughness has been developed. The steel has been processed using a novel two step austempering process.

Materials Science and Technology, 2006 The predicted processing window has been used to select temperature–time parameters for austempering of a 3·39C–2·28Si–0·48Mn–0·13Mo–0·23Cu–0·05Ni–0·034Mg (wt-%) ductile iron. Comparison of a single step austempering with two step high–low temperature regime has been carried out.
