... to deliver mechanical properties equivalent to that of the parent material, this is largely based on the results of tensile or accelerated creep tests for most gas turbine hot section components failure occurs as a result of thermal fatigue or thermomechanical fatigue. The damage that occurs under...

...M. Aghaie-Khafri; S. Farahany Creep degradation of an IN738C superalloy after long-term thermal exposure in an atmospheric furnace was investigated by means of accelerated creep tests. Experimental observation showed that the minimum creep rate increased by increasing the exposure time or exposure...

.... Life prediction based on test data of this investigation shows good agreement with actual flight experience of these blades. The method of this article provides a new way to estimate the potential creep-fatigue or low cycle fatigue life for turbine blades. blades creep testing directional...

... 15 May 2000 gas turbines manufacturing industries creep testing materials testing metallurgy stress relaxation Design for Performance is a recently developed methodology for evaluating the creep strength and fracture resistance of high temperature materials 1 . Whereas...

... particles creep testing fatigue fatigue testing creep manufacturing processes costing During the past three years, Composite Optics, Inc. (COI) has developed oxide–oxide ceramic matrix composites (CMCs) for advanced military aircraft, with potential applications in commercial gas turbine...

...David A. Woodford; Andrew A. Wereszczak; Wate T. Bakker A new approach to tensile creep testing and analysis based on stress relaxation is described for sintered silicon nitride. Creep rate data covering up to five orders of magnitude were generated in tests lasting less than one day. Tests from...

...) and the dynamic Young’s modulus as a function of temperature, determined by the resonant frequency method up to about 1300°C in air as well as analyzed by the creep tests at 1400°C in air. 4 Fracture toughness and hardness of hot-pressed SiC-SN-materials Also the hardness shows a clear dependency...
