چکیده

Abstract The structural stability of ausferrite in thin-walled Austempered Ductile Iron (ADI) castings with 5 mm wall thickness is compared to a reference casting 25 thickness. and were first austenitized between 850 925 °C, then austempered 250 380 °C. X-ray diffraction (XRD) investigations changing temperature performed − 260 up + 450 °C investigate the change phase fraction, lattice parameters strain ausferrite. role austenitization on homogeneity investigated ADI has been provided. In addition, problem occurrence “blocky” high-carbon austenite that was not completely involved during austempering, taken into account. Finally, it shown provided higher if castings.

Structural and Mechanical Characterization of Austempered Cu - Sn Ductile Iron Alloys

The effect of heat treatment and alloying elements of copper and tin on the microstructure and mechanical properties of austempered ductile cast iron alloys is investigated. The austenitizing temperature of 890°C, the isothermal transformation (austempering) temperatures of 285, 335 and 375°C, and austempering times of 15, 30, 75 and 150 minutes are studied. The alloying elements of copper and ...

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 ...
