Wear Of Materials 1979

Understanding the composition and structure of a surface is essential in understanding its frictional (Tribological) properties. This volume in the Materials Characterization series will focus on surface characterization, including roughness, hardness, coating thickness and bond strength. Advanced characterization methods are also covered for applications in magnetic recording media, rolling contact bearings and other high-tech systems. -- Reviews major physical principles of tribology, including adhesion, friction, abrasion and surface boundary conditions -- Special section on surface characterization of magnetic recording surfaces -- Concise summaries of major characterization technologies for tribological materials, including SEM, Energy-Dispersive X-Ray Spectroscopy, Fourier Transform Infrared Spectroscopy and Static Secondary Ion Mass Spectroscopy

In an attempt to meet the demand for new ultra-high strength materials, the processing of novel material configurations with unique microstructure is being explored in systems which are further and further from equilibrium. One such class of emerging materials is the so-called nanophased or nanostructured materials. This class of materials includes metals and alloys, ceramics, and polymers characterized by controlled ultra-fine microstructural features in the form oflayered, fibrous, or phase and grain distribution. While it is clear that these materials are in an early stage of development, there is now a sufficient body of literature to fuel discussion of how the mechanical properties and deformation behavior can be controlled through control of the microstructure. This NATO-Advanced Study Institute was convened in order to assess our current state of knowledge in the field of mechanical properties and deformation behavior in materials with ultra fine microstructure, to identify opportunities and needs for further research, and to identify the potential for technological applications. The Institute was the first international scientific meeting devoted to a discussion on the mechanical properties and deformation behavior of materials having grain sizes down to a few nanometers. Included in these discussions were the topics of superplasticity, tribology, and the supermodulus effect. Lectures were also presented which covered a variety of other themes including synthesis, characterization, thermodynamic stability, and general physical properties.

Mechanisms of wear, friction and lubrication are comprehensively described in an accessible manner that is designed to be helpful to non-specialists. The control of wear is given extensive treatment with a thorough discussion of lubricant additives, solid lubricants and surface coatings. The effectiveness of coatings in suppressing specific forms of wear is described together with the methods of coating deposition. More than 1000 references are provided to give the reader access to more specialized information if required.

Strength of Metals and Alloys, Volume 3 (ICSMA 7) presents the proceedings of the 7th International Conference on the Strength of Metals and Alloys held in Montreal, Canada on August 12-16, 1985. The book includes papers on the work hardening of face-centered cubic single crystals; precipitation hardening; and microstructure evolution and flow stress during hot working. The text also covers papers on microstructure evolution and flow stress during hot working; the prediction of deformation textures in cubic metals; creep of copper-base shape memory alloys; and flow behavior of nickel-base superalloys at isothermal forging temperatures and strain rates. Grain refinement by recrystallization hot-rolling to achieve high strength and notch toughness in microalloyed steel plate; as well as the influence of mean stress on fatigue strength of TI-6A1-4V are also encompassed. The book further includes papers on the comparative mechanical properties of human bones; the effect of precipitation hardening on the decomposition of the solid solution in 7075 alloy during quenching; and the mechanical properties of stable and unstable austenitic stainless steels.

As with the previous edition, the third edition of Engineering Tribology provides a thorough understanding of friction and wear using technologies such as lubrication and special materials. Tribology is a complex topic with its own terminology and specialized concepts, yet is vitally important throughout all engineering disciplines, including mechanical design, aerodynamics, fluid dynamics and biomedical engineering. This edition includes updated material on the hydrodynamic aspects of tribology as well as new advances in the field of biotribology, with a focus throughout on the engineering applications of tribology.This book offers an extensive range if illustrations which communicate the basic concepts of tribology in engineering better than text alone. All chapters include an extensive list of references and citations to facilitate further in-depth research and thorough navigation through particular subjects covered in each chapter. Includes newly devised end-of-chapter problems Provides a comprehensive overview of the mechanisms of wear, lubrication and friction in an accessible manner designed to aid non-specialists Gives a reader-friendly approach to the subject using a graphic illustrative method to break down the typically complex problems associated with tribology

Explains the mechanisms governing flow-induced vibrations and helps engineers prevent fatigue and fretting-wear damage at the design stage Fatigue or fretting-wear damage in process and plant equipment caused by flow-induced vibration can lead to operational disruptions, lost production, and expensive repairs. Mechanical engineers can help prevent or mitigate these problems during the design phase of high capital cost plants such as nuclear power stations and petroleum refineries by performing thorough flow-induced vibration analysis. Accordingly, it is critical for mechanical engineers to have a firm understanding of the dynamic parameters and the vibration excitation mechanisms that govern flow-induced vibration. Flow-Induced Vibration Handbook for Nuclear and Process Equipment provides the knowledge required to prevent failures due to flow-induced vibration at the design stage. The product of more than 40 years of research and development at the Canadian Nuclear Laboratories, this authoritative reference covers all relevant aspects of flow-induced vibration technology, including vibration failures, flow velocity analysis, vibration excitation mechanisms, fluidelastic instability, periodic wake shedding, acoustic resonance, random turbulence, damping mechanisms, and fretting-wear predictions. Each in-depth chapter contains the latest available lab data, a parametric analysis, design guidelines, sample calculations, and a brief review of modelling and theoretical considerations. Written by a group of leading experts in the field, this comprehensive single-volume resource: Helps readers understand and apply techniques for preventing fatigue and fretting-wear damage due to flow-induced vibration at the design stage Covers components including nuclear reactor internals, nuclear fuels, piping systems, and various types of heat exchangers Features examples of vibration-related failures caused by fatigue or fretting-wear in nuclear and process equipment Includes a detailed overview of state-of-the-art flow-induced vibration technology with an emphasis on two-phase flow-induced vibration Covering all relevant aspects of flow-induced vibration technology, Flow-Induced Vibration Handbook for Nuclear and Process Equipment is required reading for professional mechanical engineers and researchers working in the nuclear, petrochemical, aerospace, and process industries, as well as graduate students in mechanical engineering courses on flow-induced vibration.

The Running-In Process in Tribology is a collection of papers presented during the 8th Leeds-Lyon Symposium on Tribology held in the Institut National des Sciences Appliquées de Lyon, France in September 1981. The symposium was attended by 87 delegates from 13 countries, which showed a great level of interest on the scientific and industrial problems of running-in. Twenty eight papers are presented in the book, covering basic thermodynamics, mechanics of continuous solids, metallurgy, polymers, profilometry, and surface physics. Major topics such as elastohydrodynamics, roughness, and thermal effects in tribology are discussed as well. Mechanical engineers and materials scientists will find the book very insightful.
