RISCarbide Precipitation in the Microstructures of Austempered Ductile Irons Containing 0.48% and 4.88% Al
The influence of aluminium on the microstructure of austempered ductile cast iron (ADI) has been studied. The presences of well distributed graphite in the matrix, and a relatively high volume fraction of retained austenite, are responsible...
The Bainite Transformation and the Carbide Precipitation of 4.88% Aluminium Austempered Ductile Iron Investigated Using Electron Microscopy
The transformation to a bainitic microstructure during austempering under different conditions was examined for the most successful of the experimental casts. Austenitising temperature of 920C and austempering temperatures of 350C for different...
The Influence of Variation Bainite Morphology on the Mechanical Properties of NiCrMo (BOZ) Steel
One of the most effective ways to increase strength and toughness in steels is forming bainite phase through austempering heat treatment. In this study, the effect of bainite morphology on steel containing chromium, nickel, and molybdenum (Din:34Cr...
