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 ...
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 کاملPearlitic ductile cast iron: damaging micromechanisms at crack tip
Ductile cast irons (DCIs) are characterized by a wide range of mechanical properties, mainly depending on microstructural factors, as matrix microstructure (characterized by phases volume fraction, grains size and grain distribution), graphite nodules (characterized by size, shape, density and distribution) and defects presence (e.g., porosity, inclusions, etc.). Versatility and higher performa...
متن کاملAn image segmentation for the measurement of microstructures in ductile cast iron
The work is applying an image segmentation to a micrograph which is showing the microscopic structures of a specimen of ductile cast iron. The segmentation allows the measurement of the size of the nodules.
متن کاملDevelopment of a Ferritic Ductile Cast Iron for Increased Life in Exhaust Applications
The ship is safest when it is in port, but that's not what ships were built for. ABSTRACT Due to coming emission legislations, the temperature is expected to increase in heavy-duty diesel engines, specifically in the hot-end of the exhaust system affecting components, such as exhaust-and turbo manifolds. Since the current material in the turbo manifold, a ductile cast iron named SiMo51, is oper...
