Development of a Freckle Predictor via Rayleigh Number Method for Single-Crystal Nickel-Base Superalloy Castings
A Rayleigh number based criterion is developed for predicting the formation of freckles in Ni-base superalloy castings. This criterion relies on finding the maximum local Rayleigh number in the mush, where the ratio of the driving buoyancy force to the retarding frictional force is the largest. A critical Rayleigh number for freckle formation of approximately 0.25 is found from available experi...
متن کاملHigh Temperature Deformation Mechanisms in a DLD Nickel Superalloy
The realisation of employing Additive Layer Manufacturing (ALM) technologies to produce components in the aerospace industry is significantly increasing. This can be attributed to their ability to offer the near-net shape fabrication of fully dense components with a high potential for geometrical optimisation, all of which contribute to subsequent reductions in material wastage and component we...

متن کاملCrystal plasticity and crack initiation in a single-crystal nickel-base superalloy Modelling, evaluation and applications
In this dissertation the work done in the projects KME-410/502 will be presented. The overall objective in these projects is to evaluate and develop tools for designing against fatigue in single-crystal nickel-base superalloys in gas turbines. Experiments have been done on single-crystal nickel-base superalloy specimens in order to investigate the mechanical and fatigue behaviour of the materia...
متن کاملModelling plastic deformation in a single-crystal nickel-based superalloy using discrete dislocation dynamics
Background: Nickel-based superalloys are usually exposed to high static or cyclic loads in non-ambient environment, so a reliable prediction of their mechanical properties, especially plastic deformation, at elevated temperature is essential for improved damage-tolerance assessment of components. Methods: In this paper, plastic deformation in a single-crystal nickel-based superalloy CMSX4 at el...
