This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research has been to develop a fundamental understanding of the high temperature deformation, fracture, and fatigue crack growth resistance of single crystals of NiAl and NiAl-based intermetallic alloys. The approach we have taken involves high resolution mechanical property studies of well-characterized and well-oriented single crystals of NiAl containing various alloying elements (Ti, Fe, Zr) in the form of both solid solutions and two phase alloys. Our studies of the high temperature deformation of the solid-solution alloy Ni-Al(Ti) revealed a significant solute strengthening effect which we studied, characterized and modeled. The creep rates for these alloys were observed to be independent of crystal orientation and were as much as three to four orders of magnitude lower than for unalloyed NiAl. We have also studied the unusual creep properties of Ni3Al, a related intermetallic alloy, at intermediate temperatures. We have also conducted the first-ever studies of the cyclic fatigue crack-growth behavior of NiAl single crystals at both room temperature and 800 deg C. Room temperature crack growths ranged over two orders of magnitude from 10-8 to 10-10 m/cycle with a fatigue threshold value DKTH of approximately 2.3 MPaOem. Similar crack growths at 800 deg C required DK of about 8 MPaOem.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the work of this research program was to obtain an understanding of the mechanisms that control high temperature deformation in metal single crystals containing non-deformable particles. This objective was motivated by the belief that the presence of grain boundaries invariably degrades the creep and rupture properties of commercial dispersion strengthened metals and confuses efforts to understand their properties. The authors believe this work has made it easier to understand the unusual properties of dispersion strengthened metals. The main thrust of experimental work has been on single crystals of Ni-20Cr-2ThO2.

Download or read book Creep of Crystals written by Jean-Paul Poirier and published by Cambridge University Press. This book was released on 1985-02-28 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook describes the physics of the plastic deformation of solids at high temperatures. It is directed at geologists or geophysicists interested in the high-temperature behaviour of crystals who wish to become acquainted with the methods of materials science in so far as they are useful to earth scientists. It explains the most important models and recent experimental results without losing the reader in the primary literature of materials science. In turn the book deals with the essential solid-state physics; thermodynamics and hydrostatics of creep; creep models and their applications in the geological sciences; diffusion creep; superplastic deformation and deformation enhanced by phase transformations. Five concluding chapters give experimental results for metals, ceramics and minerals. There are extensive bibliographies to aid further study.

This book was released on 2012-12-06 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: The attractive physical and mechanical properties of ordered intermetallic alloys have been recognized since early in this century. However, periodic attempts to develop intermetallics for structural applications were unsuc cessful, due in major part to the twin handicaps of inadequate low-temper ature ductility or toughness, together with poor elevated-temperature creep strength. The discovery, in 1979, by Aoki and Izumi in Japan that small additions of boron caused a dramatic improvement in the ductility of Ni3Al was a major factor in launching a new wave of fundamental and applied research on intermetallics. Another important factor was the issuance in 1984 of a National Materials Advisory Board reported entitled "Structural Uses for Ductile Ordered Alloys," which identified numerous potential defense-related applications and proposed the launching of a coordinated development program to gather engineering property and processing data. A substantial research effort on titanium aluminides was already underway at the Air Force Materials Laboratory at Wright Patterson Air Force Base in Ohio and, with Air Force support, at several industrial and university laboratories. Smaller programs also were under way at Oak Ridge National Laboratory, under Department of Energy sponsorship. These research efforts were soon augmented in the United States by funding from Department of Defense agencies such as Office of Naval Research and Air Force Office of Scientific Research, and by the National Science Foundation.

Available in PDF, EPUB and Kindle. Book excerpt: This volume of proceedings is concerned with an increasingly important area, that of intermetallics and high temperature aluminides, which has recently been attracting a great deal of attention. Nearly 150 papers presented at the meeting held in San Diego in September 1991 are reproduced here. They cover a wide range of related topics such as the bonding characteristic and alloying behaviour of TiA1 intermetallic compounds and the cleavage fracture of ordered intermetallic alloys. All the papers have been reviewed according to the standards set by Materials Science and Engineering. This book will be of interest to metallurgists and materials scientists working with composites who are interested in the latest developments in this fast–moving field.

This book was released on 2018-07-17 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intermetallic compound NiAl is one of many advanced materials which is being scrutinized for possible use in high temperature, structural applications. Stoichiometric NiAl has a high melting temperature, excellent oxidation resistance, and good thermal conductivity. Past research has concentrated on improving monotonic properties. The encouraging results obtained on binary and micro-alloyed NiAl over the past ten years have led to the broadening of NiAl experimental programs. The purpose of this research project was to determine the low cycle fatigue properties and dislocation mechanisms of stoichiometric NiAl at temperatures near the monotonic brittle-to-ductile transition. The fatigue properties were found to change only slightly in the temperature range of 600 to 700 K; a temperature range over which monotonic ductility and fracture strength increase markedly. The shape of the cyclic hardening curves coincided with the changes observed in the dislocation structures. The evolution of dislocation structures did not appear to change with temperature.
