Download or read book Creep and High Temperature Deformation of Metals and Alloys written by Stefano Spigarelli and published by MDPI. This book was released on 2019-12-12 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the late 1940s, and since then, the continuous development of dislocation theories have provided the basis for correlating the macroscopic time-dependent deformation of metals and alloys—known as creep—to the time-dependent processes taking place within the metals and alloys. High-temperature deformation and stress relaxation effects have also been explained and modeled on similar bases. The knowledge of high-temperature deformation as well as its modeling in conventional or unconventional situations is becoming clearer year by year, with new contemporary and better performing high-temperature materials being constantly produced and investigated. This book includes recent contributions covering relevant topics and materials in the field in an innovative way. In the first section, contributions are related to the general description of creep deformation, damage, and ductility, while in the second section, innovative testing techniques of creep deformation are presented. The third section deals with creep in the presence of complex loading/temperature changes and environmental effects, while the last section focuses on material microstructure–creep correlations for specific material classes. The quality and potential of specific materials and microstructures, testing conditions, and modeling as addressed by specific contributions will surely inspire scientists and technicians in their own innovative approaches and studies on creep and high-temperature deformation.

Download or read book Small Scale Deformation using Advanced Nanoindentation Techniques written by Ting Tsui and published by MDPI. This book was released on 2019-06-11 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small scale mechanical deformations have gained a significant interest over the past few decades, driven by the advances in integrated circuits and microelectromechanical systems. One of the most powerful and versatile characterization methods is the nanoindentation technique. The capabilities of these depth-sensing instruments have been improved considerably. They can perform experiments in vacuum and at high temperatures, such as in-situ SEM and TEM nanoindenters. This allows researchers to visualize mechanical deformations and dislocations motion in real time. Time-dependent behavior of soft materials has also been studied in recent research works. This Special Issue on "Small Scale Deformation using Advanced Nanoindentation Techniques"; will provide a forum for researchers from the academic and industrial communities to present advances in the field of small scale contact mechanics. Materials of interest include metals, glass, and ceramics. Manuscripts related to deformations of biomaterials and biological related specimens are also welcome. Topics of interest include, but are not limited to: Small scale facture Nanoscale plasticity and creep Size-dependent deformation phenomena Deformation of biological cells Mechanical properties of cellular and sub-cellular components Novel mechanical properties characterization techniques New modeling methods Environmentally controlled nanoindentation In-situ SEM and TEM indentation
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 2019 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoindentation is a commonly used technique in materials science that allows for the determination of the mechanical properties (e.g. hardness, elastic modulus, and creep) of single crystals and polycrystalline aggregates, but it has been severely underutilized for the study of geologic materials. In this dissertation, we demonstrate the effectiveness of nanoindentation for measuring the rheological behavior of a wide range of geologic materials. For all materials tested, including single crystals, polycrystalline samples, and two different natural fault surfaces, we identify an 'indentation size effect,' whereby the strength of the material increases with decreasing size of the indent. We explore the implications of this size effect for the scale-dependent surface roughness of faults and the plastic deformation of asperities in Chapter 2, and extrapolate the size effect to the relatively large grain size of the mantle to predict the peak strength of oceanic lithosphere in Chapter 3. In Chapter 4, we investigate the effect of relative humidity on the room temperature deformation of quartz in order to constrain the physical mechanism that gives rise to time-dependent increases in the static friction of quartz rocks. Our results demonstrate that there is no effect of relative humidity on the yield stress or creep behavior of quartz, in stark contrast with observations from macroscopic friction experiments on quartz rocks that show a dramatic effect of humidity on friction. This contrast demonstrates that asperity creep, the canonical explanation of the increase in static friction with time, is incorrect. Finally, in Chapter 5, we present a detailed nanoindentation study of the hardness and long duration creep behavior of halite. We demonstrate that creep parameters derived from our nanoindentation tests, when properly treated, are in quantitative agreement and can be directly compared to creep parameters derived from more traditional experimental geometries. This dissertation demonstrates the utility of using nanoindentation to determine physical properties and rheological behavior of rocks and minerals.

Download or read book Crystal Plasticity at Micro and Nano scale Dimensions written by Ronald W. Armstrong and published by MDPI. This book was released on 2021-08-31 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present collection of articles focuses on the mechanical strength properties at micro- and nanoscale dimensions of body-centered cubic, face-centered cubic and hexagonal close-packed crystal structures. The advent of micro-pillar test specimens is shown to provide a new dimensional scale for the investigation of crystal deformation properties. The ultra-small dimensional scale at which these properties are measured is shown to approach the atomic-scale level at which model dislocation mechanics descriptions of crystal slip and deformation twinning behaviors are proposed to be operative, including the achievement of atomic force microscopic measurements of dislocation pile-up interactions with crystal grain boundaries or with hard surface coatings. A special advantage of engineering designs made at such small crystal and polycrystalline dimensions is the achievement of an approximate order-of-magnitude increase in mechanical strength levels. Reasonable extrapolation of macro-scale continuum mechanics descriptions of crystal strength properties at micro- to nano-indentation hardness measurements are demonstrated, in addition to reports on persistent slip band observations and fatigue cracking behaviors. High-entropy alloy, superalloy and energetic crystal properties are reported along with descriptions of deformation rate sensitivities, grain boundary structures, nano-cutting, void nucleation/growth micromechanics and micro-composite electrical properties.
