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 کاملDevelopment 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 کاملX-ray Stress Measurement of Nickel-base Single Crystal Superalloy Using Two-dimensional Detector
The stress in a single crystal of nickel-base superalloy with 72 % volume fraction of '-phase was measured by the X-ray method. The specimen whose surface normal was parallel to [001] direction was oscillated around -axis during recording of the X-ray diffraction pattern with a two-dimensional position sensitive proportional counter (PSPC). The stress was determined from the measured strain u...
