Automatic Quantitative Analysis of Microstructure of Ductile Cast Iron Using Digital Image Processing
Ductile cast iron is preferred as nodular iron or spheroidal graphite iron. Ductile cast iron contains graphite in form of discrete nodules and matrix of ferrite and perlite. In order to determine the mechanical properties, one needs to determine volume of phases in matrix and nodularity in the microstructure of metal sample. Manual methods available for this, are time consuming and accuracy de...
متن کاملCasting and stress-strain simulations of a cast ductile iron component using microstructure based mechanical behavior
The industrial demand for increased component performance with concurrent reductions in component weight, development times and verifications using physical prototypes drives the need to use the full potential of casting and Finite Element Method (FEM) simulations to correctly predict the mechanical behavior of cast components in service. The mechanical behavior of the component is determined b...
متن کاملNDT of Ductile Cast Iron from Nuclear Waste Storage Canisters
The concept for geological disposal of nuclear waste and spent nuclear fuel relies on a multi-barrier system with the copper/cast iron canister as the first barrier. The canister is designed to retain its integrity for at least 100000 years, which means that future glaciations need to be considered. A thick ice block together with hydrostatic pressure from groundwater would produce hydrostatic ...
متن کاملFatigue Performance of Forged Steel and Ductile Cast Iron Crankshafts
Fatigue is the primary cause of failure of crankshafts in internal combustion engines. The cyclic loading conditions and the stress concentrations in the crank pin fillets are unavoidable, and can result in fatigue failure. The objectives of this study were to compare the fatigue behavior of forged steel and ductile iron crankshafts from a one-cylinder engine as well as to determine if the fati...
متن کاملMicrostructure and Sliding Wear Behaviour of In-Situ TiC-Reinforced Composite Surface Layers Fabricated on Ductile Cast Iron by Laser Alloying
TiC-reinforced composite surface layers (TRLs) on a ductile cast iron EN-GJS-700-2 grade (DCI) substrate were synthesized using a diode laser surface alloying with a direct injection of titanium powder into the molten pool. The experimental results were compared with thermodynamic calculations. The TRLs having a uniform distribution of the TiC particles and their fraction up to 15.4 vol % were ...
