Download or read book Precipitate Coarsening During Overaging of 2519 Al Cu Alloy Application to Superplastic Processing written by and published by . This book was released on 1992 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overaging experiments have been conducted on a commercial grade 2519 Al-Cu alloy at a variety of temperatures and times, with and without prior induced strain. Hardness testing and scanning electron microscopy techniques were used to characterize evolution of microstructure during overaging. The further development of microstructure during thermomechanical processing by warm rolling was also assessed to determine whether the coarse particles produced by overaging could serve as sites for particle stimulated nucleation (PSN) of recrystallization. The thermomechanical processing methods have been shown to produce highly superplastic microstructures in Al-Mg and Al-Mg-Li alloys in previous work at NPS. Optical microscopy and tensile tests were conducted allowing a determination of the effect of the processing on the microstructural evolution and superplastic behavior of the Al-Cu material.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 426 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 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination 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 concerned if the printing and distribution of the volumes were handled by an international 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 Corporation 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 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Study of Precipitation and Recrystallization in A1 Alloy 2519 by Backscattered Electron Imaging Methods written by Peter Joseph Zohorsky and published by . This book was released on 1993 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the effects of pre-strain deformation temperature, overaging temperature, and other variations in thermomechanical processing (TMP) on the mean size and size distribution of q-phase precipitate particles in Al alloy 2519. Examination was performed using the scanning electron microscope in the backscattered imaging mode and quantitative image analysis methods were employed. The goal was to find a combination of TMP parameters which produces q-phase particles exceeding a critical diameter for particle stimulated nucleation (PSN) of recrystallization. A necessary prerequisite for superplasticity is a uniformly fine, equiaxed grain size and PSN is theorized to be capable of such grain refinement. Such a microstructure has been developed in Aluminum alloys containing large second phase particles when the alloys are subjected to cold work and recrystallization treatments.

Download or read book Friction Stir Welding of Aluminium Alloys written by Moataz Attallah and published by LAP Lambert Academic Publishing. This book was released on 2011-02 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Friction Stir Welding (FSW) is known to result in a complex microstructural development, with features that remain unexplained, such as: the formation of the onion rings structure. Moreover, various microstructural factors have been suggested to control the strength in Al-Mg AA5xxx welds, without identifying their relative contribution. Furthermore, the influence of the basemetal microstructural parameters (e.g. grains, intermetallic particles, stored energy) on the microstructure-property development has not been previously investigated. These issues are addressed in the present study.

Download or read book Friction Stir Welding written by Daniela Lohwasser and published by Elsevier. This book was released on 2009-12-18 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Friction stir welding (FSW) is a highly important and recently developed joining technology that produces a solid phase bond. It uses a rotating tool to generate frictional heat that causes material of the components to be welded to soften without reaching the melting point and allows the tool to move along the weld line. Plasticized material is transferred from the leading edge to trailing edge of the tool probe, leaving a solid phase bond between the two parts. Friction stir welding: from basics to applications reviews the fundamentals of the process and how it is used in industrial applications.Part one discusses general issues with chapters on topics such as basic process overview, material deformation and joint formation in friction stir welding, inspection and quality control and friction stir welding equipment requirements and machinery descriptions as well as industrial applications of friction stir welding. A chapter giving an outlook on the future of friction stir welding is included in Part one. Part two reviews the variables in friction stir welding including residual stresses in friction stir welding, effects and defects of friction stir welds, modelling thermal properties in friction stir welding and metallurgy and weld performance.With its distinguished editors and international team of contributors, Friction stir welding: from basics to applications is a standard reference for mechanical, welding and materials engineers in the aerospace, automotive, railway, shipbuilding, nuclear and other metal fabrication industries, particularly those that use aluminium alloys. - Provides essential information on topics such as basic process overview, materials deformation and joint formation in friction stir welding - Inspection and quality control and friction stir welding equipment requirements are discussed as well as industrial applications of friction stir welding - Reviews the variables involved in friction stir welding including residual stresses, effects and defects of friction stir welds, modelling thermal properties, metallurgy and weld performance
