This book was released on 2009 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanocrystalline (nc) materials are characterized by a grain size in the range 1-200 nm. Because of this characteristic, these materials exhibit unique microstructures in which the volume of grain boundaries is significant. Nc-materials offer interesting possibilities related to many structural applications. In order to explore some of these possibilities, an understanding of the origin of mechanical properties such as strength, hardness, and ductility is essential. Mechanical properties in materials are very sensitive to their microstructure. One important process that can be used to manipulate the details microstructure in materials is annealing. In the present dissertation, annealing treatment was utilized to provide insight into the correlation between mechanical properties and microstructure. Primary among the mechanical properties that were selected for investigation are hardness, the elastic modulus, strength and ductility. Experiments on hardness and the modulus of elasticity were conducted at room temperature on samples of electrodeposited (ED) nc-Ni that were annealed at temperatures ranging from 323 K to 693 K. The results showed the presence of three regions: regions I, II, and III. In region I (300 K T 350 K), hardness and the elastic modulus remained essentially constant. In region II (350

Download or read book Experimental Study of the Microstructural Evolution of Chemical Vapor Deposited Nickel Upon Annealing written by Chen Chichi and published by . This book was released on 2011 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of annealing conditions on the microstructure evolution of CVD nickel was investigated systematically in the present study by differential scanning calorimetry, optical microscopy and transmission electron microscopy (TEM), upon both ex-situ and in-situ annealing. TEM observation revealed the as-deposited CVD nickel possessed a bi-modal grain structure, with large columnar grains embedded in nanocrystalline matrix. Ultrafine and nano growth twins were present as well as multiply twinned grains with five-fold symmetry. Microstructure observation upon annealing showed that grain growth did not occur until annealing at 400oC. Detwinning was observed at 400oC and higher temperatures. The ultrafine and nano twins tended to transform into dislocation cell structures and this phenomenon was driven by the excess free energy associated with the high density of grown-in twin boundaries. The five-fold twinned grains were found to be thermally stable up to 600oC. The hardness was observed to decrease with increasing annealing temperature.

Download or read book Physical and Mechanical Properties of Electroformed Nickel at Elevated and Subzero Temperatures written by C. H. Sample and published by . This book was released on 1962 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electroforming is a well-established electrodeposition process for producing both simple and complex shaped articles to extremely close dimensional tolerances and to exacting surface requirements. The process is applicable to the production of not only small, thin-walled parts but also large objects of substantial cross-section. There are considerable data in the literature on mechanical properties of electroformed nickel at room temperature (1-4), but very little information is available on properties at elevated or subzero temperatures. The lack of such data has been a serious handicap to design engineers and electroformers. Consequently a research program was initiated to provide pertinent information for nickel deposited from a few typical but basically different plating baths, which are known to yield deposits of differing microstructures and mechanical properties at room temperature. The purpose of this paper is to present the information accumulated to date.

Download or read book The Effects of Annealing on the Microstructure and Mechanical Properties of Fe28Ni18Mn33Al21 written by and published by . This book was released on 2015 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, As-cast Fe28Ni18Mn33Al21, which consists of aligned, 50 nm, (Ni, Al)-rich B2, and (Fe, Mn)-rich f.c.c. phases, was annealed at a variety of temperatures up to 1423 K and the microstructure and mechanical properties were examined. It was shown that the as-cast microstructure arises from a eutectoid transformation at ~1300 K. Annealing at temperatures d"073 K produces [beta]-Mn-structured precipitates and hardness values up to 816 HV, while annealing at temperatures>1073 K leads to dramatic coarsening of the two-phase B2/f.c.c. microstructure (up to 5.5 æm after 50 h at 1273 K), but does not lead to [beta]-Mn precipitation. Interestingly, annealing at temperatures>1073 K delays the onset of [beta]-Mn precipitation during subsequent anneals at lower temperatures. Coarsening the B2/f.c.c. lamellar structure by annealing at higher temperatures softens it and leads to increases in ductility from fracture before yield to ~8 % elongation. Finally, the presence of [beta]-Mn precipitates makes the very fine, brittle B2/f.c.c. microstructures even more brittle, but significant ductility (8.4 % elongation) is possible even with [beta]-Mn precipitates present if the B2/f.c.c. matrix is coarse and, hence, more ductile.

Download or read book Fundamentals of Materials Science written by Eric J. Mittemeijer and published by Springer Nature. This book was released on 2022-01-01 with total page 754 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook offers a strong introduction to the fundamental concepts of materials science. It conveys the quintessence of this interdisciplinary field, distinguishing it from merely solid-state physics and solid-state chemistry, using metals as model systems to elucidate the relation between microstructure and materials properties. Mittemeijer's Fundamentals of Materials Science provides a consistent treatment of the subject matter with a special focus on the microstructure-property relationship. Richly illustrated and thoroughly referenced, it is the ideal adoption for an entire undergraduate, and even graduate, course of study in materials science and engineering. It delivers a solid background against which more specialized texts can be studied, covering the necessary breadth of key topics such as crystallography, structure defects, phase equilibria and transformations, diffusion and kinetics, and mechanical properties. The success of the first edition has led to this updated and extended second edition, featuring detailed discussion of electron microscopy, supermicroscopy and diffraction methods, an extended treatment of diffusion in solids, and a separate chapter on phase transformation kinetics. “In a lucid and masterly manner, the ways in which the microstructure can affect a host of basic phenomena in metals are described.... By consistently staying with the postulated topic of the microstructure - property relationship, this book occupies a singular position within the broad spectrum of comparable materials science literature .... it will also be of permanent value as a reference book for background refreshing, not least because of its unique annotated intermezzi; an ambitious, remarkable work.” G. Petzow in International Journal of Materials Research. “The biggest strength of the book is the discussion of the structure-property relationships, which the author has accomplished admirably.... In a nutshell, the book should not be looked at as a quick ‘cook book’ type text, but as a serious, critical treatise for some significant time to come.” G.S. Upadhyaya in Science of Sintering. “The role of lattice defects in deformation processes is clearly illustrated using excellent diagrams . Included are many footnotes, ‘Intermezzos’, ‘Epilogues’ and asides within the text from the author’s experience. This ..... soon becomes valued for the interesting insights into the subject and shows the human side of its history. Overall this book provides a refreshing treatment of this important subject and should prove a useful addition to the existing text books available to undergraduate and graduate students and researchers in the field of materials science.” M. Davies in Materials World.

Download or read book Mechanical Properties and Deformation Behavior of Materials Having Ultra Fine Microstructures written by Michael Anthony Nastasi and published by Springer Science & Business Media. This book was released on 1993 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the emerging class of new materials characterized by ultra-fine microstrucures. The NATO ASI which produced this book was the first international scientific meeting devoted to a discussion of the mechanical properties and deformation behavior of materials having grain sizes down to a few nanometers. Topics covered include superplasticity, tribology, and the supermodulus effect. Review chapters cover a variety of other themes including synthesis, characterization, thermodynamic stability, and general physical properties. Much of the work is concerned with the issue of how far conventional techniques and concepts can be extended toward atomic scale probing. Another key issue concerns the structure of nanocrystalline materials, in particular, what is the structure and composition of the internal boundaries. These ultra-fine microstructures have proved to challenge even the finest probes that the materials science community has today.

Available in PDF, EPUB and Kindle. Book excerpt: This highly illustrated reference work covers the three principal types of surface technologies that best protect engineering devices and products: diffusion technologies, deposition technologies, and other less commonly acknowledged surface engineering (SE) techniques. Various applications are noted throughout the text and additionally whole chapters are devoted to specific SE applications across the automotive, gas turbine engine (GTE), metal machining, and biomedical implant sectors. Along with the benefits of SE, this volume also critically examines SE's limitations. Materials degradation pathways - those which can and those which cannot be mitigated by SE - are rigorously explained. Written from a scientific, materials engineering perspective, this concise text is supported by high-quality images and photo-micrographs which show how surfaces can be engineered to overcome the limits of conventionally produced materials, even in complex or hostile operating environments. This book is a useful resource for undergraduate and postgraduate students as well as professional engineers.
