Numerical modelling of thin-walled hypereutectic ductile cast iron parts

Undercooling and nodule count in thin walled ductile iron castings

Experimental validation of error in temperature measurements in thin walled ductile iron castings

Layered Manufacturing of Thin-walled Parts

We describe a new algorithm we have developed for making partially hollow layered parts with thin, dense walls of approximately uniform thickness, for faster build times and reduced material usage. We have implemented our algorithm on a fused deposition modeling (FDM) machine, using separate build volumes for a loosely filled interior and a thin, solid, exterior wall. The build volumes are deri...

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...
