Download or read book Microstructural Study of the Nickel base Alloy WAZ 20 Using Qualitative and Quantitative Electron Optical Techniques written by Stanley G. Young and published by . This book was released on 1973 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NASA nickel-base alloy WAZ-20 was analyzed by advanced metallographic techniques to qualitatively and quantitatively characterize its phases and stability. The as-cast alloy contained primary gamma-prime, a coarse gamma-gamma prime eutectic, a gamma-fine gamma prime matrix, and MC carbides. A specimen aged at 870 C for 1000 hours contained these same constituents and a few widely scattered high W particles. No detrimental phases (such as sigma or mu) were observed. Scanning electron microscope, light metallography, and replica electron microscope methods are compared. The value of quantitative electron microprobe techniques such as spot and area analysis is demonstrated.

This book was released on 1968 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: An electron microstructure study was carried out to understand the precipitation behavior of age-hardening gamma-prime in an iron-nickel base high temperature alloy, Pyromet 860, containing 4 weight per cent cobalt. Carbon extraction replica and thin foil transmission electron microscopy were used. The extraction replica study showed gamma-prime to have many random orientations in addition to some preferred orientation. The thin film microscopy did not show any contrast effect due to coherency strains and confirmed many orientations of gamma-prime precipitates.

Download or read book Microstructural Characterization and Electron Microprobe Analysis of a Nickel Aluminum Bronze Laser clad Weldment written by and published by . This book was released on 1999 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, the microstructural & compositional variations were characterized across a laser-clad weldment produced with a heat input of 150 Joules/centimetre and a copper filler wire containing 9.0% aluminium, 4.6% nickel, and 3.9% manganese. The weld metal, heat-affected zone, and casting base metal structures & elemental distributions were evaluated using an optical microscope and electron microprobe, respectively. The results demonstrate the range of microstructures and compositional variations present in the laser-clad weldment investigated.

Download or read book Metallography and Microstructure in Ancient and Historic Metals written by David A. Scott and published by Getty Publications. This book was released on 1992-01-02 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: David A. Scott provides a detailed introduction to the structure and morphology of ancient and historic metallic materials. Much of the scientific research on this important topic has been inaccessible, scattered throughout the international literature, or unpublished; this volume, although not exhaustive in its coverage, fills an important need by assembling much of this information in a single source. Jointly published by the GCI and the J. Paul Getty Museum, the book deals with many practical matters relating to the mounting, preparation, etching, polishing, and microscopy of metallic samples and includes an account of the way in which phase diagrams can be used to assist in structural interpretation. The text is supplemented by an extensive number of microstructural studies carried out in the laboratory on ancient and historic metals. The student beginning the study of metallic materials and the conservation scientist who wishes to carry out structural studies of metallic objects of art will find this publication quite useful.
