The Laser Alloying Process of Ductile Cast Iron Surface with Titanium

Microstructure 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 ...

NDT 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 ...

Fatigue 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...
