... superalloys possess excellent strength and creep resistance at relatively high temperatures. These are attributes contributing to their extensive utilization in various applications in modern industry and particularly in the aerospace sector. Depending on its magnitude and nature (i.e., whether tensile...

...Sean B. Leen; Aditya Deshpande; Thomas H. Hyde This paper describes high temperature cyclic and creep relaxation testing and modeling of a high nickel-chromium material (XN40F) for application to the life prediction of superplastic forming (SPF) tools. An experimental test program to characterize...

.... The discussion on error sources is organized in four main categories: scanning system, tip-surface interaction, environment, and data processing. The discussed errors include scaling effects, squareness errors, hysteresis, creep, tip convolution, and thermal drift. A mathematical model of the measurement system...

... density, usually no less than 10 9 – 10 10 W / cm 2 . Significant improvements in the overall performance including wear and corrosion resistance, fatigue, and creep properties are found for IBSP treated pure Cu and 316L stainless steel, attributable to the formation of nonequilibrium microstructures...

...D. Wojnowski; Y. K. Oh; J. E. Indacochea CrMoV steels are used in high temperature and high stress sections of power plant members; their good creep resistance is impaired by welding done during fabrication of assemblies and weld repair of service damaged rotors. Occurrence of a “softening...
