Carbide 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...
The Microstructural Characteristics of Al-alloyed Ductile Irons Austempered at 400°C for 100 min
The influence of aluminium on the microstructure of austempered experimental 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...
The Effect of Cooling Rate on Bainite Phase Formation in Austempered Nickel-Molybdenum Gray Cast Iron
-Molybdenum and conducted the austenitising and austempering processes at 900 °C and 400°C for 60 minutes respectively. The way of bainite phase formation and the effect of sample thickness, i.e. cooling rate, were examined by selecting a standard staircase sample...
The Influence of Austempering Temperature on Properties of Ni-Mo Gray Cast Iron
Austempering, as a proper heat treatment process for providing desired characteristics through forming bainite Phase in Cast Iron pieces, has always been a matter of concern for researchers and industrialists. In this study, a considerable number...
