RISEffect of aluminum on stability of retained austenite in bainitic ductile cast iron
The effect of aluminum additives on the microstructure of bainitic malleable cast iron after heat treatment consisting of isothermal hardening at 350°C in a bath with molten lead after a hold at 920°C for 90 min is studied. A metallographic study...
Effect of aluminum on stability of retaine austenite in bainitic malleable cast iron
The presence of well distributed graphite in the matrix, and a relatively high volume fraction of retained austenite, are responsible for the good mechanical properties of the austempered ductile irons including excellent ...
The Effect of Cooling Rate on Bainite Phase Formation in Austempered Nickel-Molybdenum Gray Cast Iron
Taking into account the importance of the amount of bainite phase on the microstructure of cast irons and its influence on the improvement of mechanical properties, this research selected an alloy of gray cast iron containing Nickel...
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...
The effect of graphite shape on vacuum-free diffusion bonding of ST37 steel and nodular cast iron
In this study, a low carbon steel (ST37) and tow kind of ductile cast iron with different nodularities, were diffusion bonded at the temperature 850 ۫C for 10 hours and then cooled in the furnace to investigate the effect of the graphite nodularity...
Determination of presence of undesirable carbides at surface of cast iron parts using differential eddy current technique
NONDESTRUCTIVE EVALUATION OF MECHANICAL PROPERTIES OF DUCTILE CAST IRON PARTS USING EDDY CURRENT SIGNALS
The present research investigates improvement of Eddy Current (EC) technique as a
nondestructive method for measurement of ductile cast iron microstructural and mechanical
characteristics. Six samples of heat treated ductile cast iron...
EVALUATION OF MICROSTRUCTURE AND MECHANICAL PROPERTIES OF HIGH-STRENGTH BAINITIC CAST IRON USING AN ELECTROMAGNETIC SENSOR
High-strength bainitic cast iron is studied after isothermal hardening at 340°C for from 0.5 to 5 h with the use
of a non-destructive eddy-current method for monitoring the microstructure and mechanical properties. Iron...
A New Approach in Solid State Steelmaking from Thin Cast Iron Sheets through Decarburization in CaCO3 Pack
of solid state steelmaking from cast iron was investigated using limestone. For
this purpose, white cast iron specimens were buried in a chamber containing CaCO3 powder. Calcination
of CaCO3 produces CO2 which participates in cast iron...
Nondestructive characterization of induction hardened cast iron parts
composition and the
microstructure of the materials under investigation, it can be used to determine the
depth of the hardened layer in steels and cast iron parts due to the difference in
magnetic properties of the hardened layer...
