This book was released on 1980 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a summary of the high temperature low cycle fatigue data for three high strength nickel-base superalloys, Rene 95, AF-115, and AF2-1DA. The majority of tests were performed in strain control at 1200 F and 1400 F, and at frequencies of 20 cpm, 0.2 cpm, and 0.05 cpm. Conventional triangular waveform was used for most of the testing although strain dwell tests and some SLOW-FAST and FAST-SLOW tests were also included. (author).

This book was released on 1988 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive characterization of low-cycle fatigue damage mechanisms was performed on polycrystalline René 80 and IN100 tested in the temperature range from 871 to 1000°C. Low-cycle fatigue life was found to be dominated by propagation of microcracks to a critical size governed by the maximum tensile stress. A model was developed which incorporates a threshold stress for crack extension, a stress-based crack growth expression, and a failure criterion. The mathematical equivalence between this mechanistically based model and the strain-life low-cycle fatigue law was demonstrated using cyclic stress-strain relationships. The model was shown to correlate the high-temperature low-cycle fatigue data of the different nickel-base superalloys considered in this study.

Book excerpt: This book covers virtually all technical aspects related to the selection, processing, use, and analysis of superalloys. The text of this new second edition has been completely revised and expanded with many new figures and tables added. In developing this new edition, the focus has been on providing comprehensive and practical coverage of superalloys technology. Some highlights include the most complete and up-to-date presentation available on alloy melting. Coverage of alloy selection provides many tips and guidelines that the reader can use in identifying an appropriate alloy for a specific application. The relation of properties and microstructure is covered in more detail than in previous books.

Available in PDF, EPUB and Kindle. Book excerpt: Due to their continuing role in electricity generation, it is important that coal power plants operate as efficiently and cleanly as possible. Coal Power Plant Materials and Life Assessment reviews the materials used in coal plants, and how they can be assessed and managed to optimize plant operation. Part I considers the structural alloys used in coal plants. Part II then reviews performance modelling and life assessment techniques, explains the inspection and life-management approaches that can be adopted to optimize long term plant operation, and considers the technical and economic issues involved in meeting variable energy demands. - Summarizes key research on coal-fired power plant materials, their behavior under operational loads, and approaches to life assessment and defect management - Details the range of structural alloys used in coal power plants, and the life assessment techniques applicable to defect-free components under operational loads - Reviews the life assessment techniques applicable to components containing defects and the approaches that can be adopted to optimize plant operation and new plant and component design

Download or read book High Temperature Low Cycle Fatigue Behavior and Lifetime Prediction of a Nickel Base ODS Alloy written by MY. Nazmy and published by . This book was released on 1988 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high-temperature low-cycle fatigue (HTLCF) behavior of mechanically alloyed oxide dispersion strengthened MA 754 nickel-base alloy was studied under strain-controlled condition at 850°C. Specimens were cut from the longitudinal and the long transverse directions of the bar stock. Triangular strain cycles as well as strain cycles with hold times were employed in this study. In general, longitudinal specimens exhibited the longest lives, long transverse specimens the shortest lives. The cycles with tensile hold times were the most damaging to the HTLCF lives of specimens of both orientations. The difference between the HTLCF response of the alloy in the longitudinal and the long transverse orientations is interpreted in terms of factors such as modes of crack initiation and propagation, anisotropy in crack growth rates, and the directionality in creep properties. Three models for HTLCF lifetime were evaluated for their ability to correlate the fatigue data on MA 754 in both orientations. These models are the Strain Range Partitioning Model (SRP), the Frequency-Separation Model (FS), and the Frequency-Modified Damage Function (FMDF). The correlations of the data, having the smallest standard deviations of 0.22 and 0.14 for the longitudinal and the long transverse orientations, respectively, were by the FS model. The FMDF and the SRP models had standard deviations, for the longitudinal orientations, of 0.25 and 0.33, respectively.
