This book was released on 2018-08-20 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alloys in the Al-Cu-Li Ag-Mg subsystem were developed that exhibit desirable combinations of strength and ductility. These Weldalite (trademark) alloys, are unique for Al-Cu-Li alloys in that with or without a prior cold stretching operation, they obtain excellent strength-ductility combinations upon natural and artificial aging. This is significant because it enables complex, near-net shape products such as forgings and super plastically formed parts to be heat treated to ultra-high strengths. On the other hand, commercial extrusions, rolled plates and sheets of other Al-Cu-Li alloys are typically subjected to a cold stretching operation before artificial aging to the highest strength tempers to introduce dislocations that provide low-energy nucleation sites for strengthening precipitates such as the T(sub 1) phase. The variation in yield strength (YS) with Li content in the near-peak aged condition for these Weldalite (trademark) alloys and the associated microstructures were examined, and the results are discussed.

This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
Download or read book Ni free Ti based Shape Memory Alloys written by Hee Young Kim and published by Butterworth-Heinemann. This book was released on 2018-09-17 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ni-free Ti-based Shape Memory Alloys reviews the fundamental issues of biomedical beta-type Ti base shape memory and superelastic alloys, including martensitic transformation, shape memory and superelastic properties, alloy development, thermomechanical treatment and microstructure control, and biocompatibility. Some unique properties, such as large nonlinear elastic behavior and low Young's modulus, observed in metastable Ti alloys are discussed on the basis of phase stability. As it is expected that superelastic Ti alloys will further expand the applications of shape memory alloys within the biomedical field, this book provides a comprehensive review of these new findings in Ti-base shape memory and superelastic alloys. - Includes coverage of phase transformations in titanium alloys - Discusses mechanical properties and alloy development - Presents a review of Ti-based shape alloys and their applications

Download or read book Cohesion in Metals written by Frank R. Boer and published by North Holland. This book was released on 1988 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. - Complete collection of phase diagrams; - Up-to-date experimental information and bibliography on thermochemical data; - Formation enthalpies as predicted by the Miedema model for binary solid and liquid solutions and compounds. The first volume in this series presents a complete collection of heat of formation data on binary intermetallic compounds that contain at least one transition metal.Both solid compounds and liquid alloys are considered. A complete table of model predictions is given for systems which lack this experimental information and the origin of the model and the accuracy of the predictions are discussed extensively. Furthermore, the authors demonstrate the applicability of the atomic model in predicting energy effects in metal science in general. When surface energies and vacancy-formation energies of pure metals and model values for enthalpies of alloying are available, one can deal with a large variety of proble

Download or read book High Temperature Deformation Behaviour of an Al Mg Si Cu Alloy and Its Relation to the Microstructural Characteristics written by Roger Nicol Carrick and published by . This book was released on 2009 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microstructural evolution and mechanical properties at elevated temperatures of a recently fabricated fine-grained AA6xxx aluminium sheet were evaluated and compared to the commercially fabricated sheet of the same alloy in the T4P condition. The behaviour of the fine-grained and T4P sheets was compared at elevated temperatures between 350°C and 550°C, as well as room temperature. Static exposure to elevated temperatures revealed that the precipitate structure of the fine-grained material did not change extensively. The T4P material, however, underwent extensive growth of precipitates, including a large amount of grain boundary precipitation. At room temperature, the T4P material deformed at much higher stresses than the FG material, but achieved lower elongations. Deformation at elevated temperatures revealed that the fine-grained material achieved significantly larger elongations to failure than the T4P material in the temperature range of 350°C-450°C. Both materials behaved similarly at 500°C and 550°C. Above 500°C, the grain size was greatly reduced in the T4P material, and only a slightly increased in the fine-grained material. At temperatures above 450°C, the elongation to failure in both materials generally increased with increasing strain-rate. The poor performance of the T4P material at low temperatures was attributed to the precipitate characteristics of the sheet, which lead to elevated stresses and increased cavitation. The deformation mechanism of both materials was found to be controlled by dislocation climb, accommodated by the self diffusion of aluminium at 500°C and 550°C. The deformation mechanism in the fine-grained material transitioned to power law breakdown at lower temperatures. At 350°C to 450°C, the T4P material behaved similarly to a particle hardened material with an internal stress created by the precipitates. The reduction in grain size of the T4P material after deformation at 500°C and 550°C was suggested to be caused by dynamic recovery/recrystallization. The role of a finer grain-size in the deformation behaviour at elevated temperatures was mainly related to enhanced diffusion through grain boundaries. The differences in the behaviour of the two materials were mainly attributed to the difference in the precipitation characteristics of the materials.
