Download or read book High Temperature Compressive Creep of Yttria Stabilized Zirconia written by Patrick K. Talty and published by . This book was released on 1975 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to define the creep behavior of yttria stabilized zirconia (YSZ) at temperatures to 2000 degrees C under conditions of stress, temperature, and environment that are encountered in storage heaters used in blow down wind tunnels. Compression creep tests were performed as a function of yttria content (in the range 10.2 to 16.5 weight percent Y2O3), density, and grain size on specimens with various impurity concentrations and porosity distributions.

Book excerpt: Tensile and compression creep measurements were made on yttria-stabilized zirconia (YSZ), hot-pressed silicon nitride and silicon materials, in atmospheres including air, nitrogen, argon and vacuum. For relatively fine-grained YSZ (below 40 microns), the 1.5 power of the applied stress at low stresses and with the stress cubed at high stresses, but results for coarse grained specimens can generally be fitted by the cube dependence. Creep activation energies for YSZ are found to be 128 kcal/mole independent of yttria content, impurity level, grain size and porosity distribution. For the silicon compounds, at least two different creep mechanisms are operative in the range of temperatures and stresses employed in this study. A grain boundary sliding mechanism, characterized by a stress dependence of two and an activation energy of 168 kcal/mole, appears to be operative for hot-pressed silicon nitride; but a viscous creep mechanism predominates for some SiAlON materials, where a linear stress dependence and an activation energy of 94 kcal/mole have been measured.

Download or read book Creep written by Tomasz Tański and published by BoD – Books on Demand. This book was released on 2018-01-10 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains 12 chapters with original and innovative research studies in the issues related to the broadly defined creep effect, which concerns not only the area of construction materials but also natural phenomena. The emphasis on the discussion of a new trend of experimental creep testing, which binds the classic creep methods to seek the correlation of parameters obtained in tests, deserves particular attention. This book aims to provide the readers, including, but not limited to, students and doctoral students and also the research personnel and engineers involved in the operation of equipment and structural components as well as specialists in high-temperature creep-resisting materials, with a comprehensive review of new trends in the field of creep-exposed materials and their research methodology. The chapters of this book were developed by respected and well-known researchers from different countries.

Download or read book Thermal Barrier Coatings Failure Theory and Evaluation Technology written by Yichun Zhou and published by Springer Nature. This book was released on 2022-10-08 with total page 943 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the failure theories and evaluation techniques of thermal barrier coatings, covering the thermal-mechanical–chemical coupling theories, performance and damage characterization techniques, and related evaluations. Thermal barrier coatings are the key thermal protection materials for high-temperature components in advanced aeroengines. Coating spallation is a major technical bottleneck faced by researchers. The extremely complex microstructure, diverse service environments, and failure behaviors bring challenges to the spallation analysis in terms of the selective use of mechanical theories, experimental methods, and testing platforms. In the book, the authors provide a systematic summary of the latest research and technological advances and present their insights and findings in the past couple of decades. This book is not only suitable for researchers and engineers in thermal barrier coatings and related fields but also a good reference for upper-undergraduate and postgraduate students of materials science and mechanics majors.

Book excerpt: Comprehensive Hard Materials, Three Volume Set deals with the production, uses and properties of the carbides, nitrides and borides of these metals and those of titanium, as well as tools of ceramics, the superhard boron nitrides and diamond and related compounds. Articles include the technologies of powder production (including their precursor materials), milling, granulation, cold and hot compaction, sintering, hot isostatic pressing, hot-pressing, injection moulding, as well as on the coating technologies for refractory metals, hard metals and hard materials. The characterization, testing, quality assurance and applications are also covered. Comprehensive Hard Materials provides meaningful insights on materials at the leading edge of technology. It aids continued research and development of these materials and as such it is a critical information resource to academics and industry professionals facing the technological challenges of the future. Hard materials operate at the leading edge of technology, and continued research and development of such materials is critical to meet the technological challenges of the future. Users of this work can improve their knowledge of basic principles and gain a better understanding of process/structure/property relationships. With the convergence of nanotechnology, coating techniques, and functionally graded materials to the cognitive science of cemented carbides, cermets, advanced ceramics, super-hard materials and composites, it is evident that the full potential of this class of materials is far from exhausted. This work unites these important areas of research and will provide useful insights to users through its extensive cross-referencing and thematic presentation. To link academic to industrial usage of hard materials and vice versa, this work deals with the production, uses and properties of the carbides, nitrides and borides of these metals and those of titanium, as well as tools of ceramics, the superhard boron nitrides and diamond and related compounds.
