Book Description
The objective of the present study is to provide a fundamental understanding of fatigue, fracture, and environmentally-assisted behavior of high-entropy alloys (HEAs). The work involves fatigue, fracture, and environmentally-assisted behavior of a new kind of advanced engineering materials, called HEAs. Three tasks are studied: (1) microstructures and fracture mechanisms of HEAs, (2) fatigue failure and life prediction of HEAs, and (3) corrosion and environmentally-assisted behavior of HEAs. In the first task, microstructural stability and fracture mechanism of the AlCoCrFeNi alloy are studied and compared with thermodynamic calculations. In the second task, high-cycle fatigue-failure mechanisms of the cold-rolled Al0.5CoCrCuFeNi alloy are explored, and the experimental results are used to develop lifetime-prediction capabilities and safety models for future applications. In the third task, a single-phase Al0.3CoCrFeNi alloy is computational-alloyed-designed and developed, and electrochemical-polarization and fatigue-environmentally-assisted behavior are investigated. Intellectual merit The current study of fatigue fracture on HEAs advances the fundamental understanding of the mechanisms of the fatigue fracture and environmentally-assisted behavior of HEAs, which is a very new area. The experimental approaches provide the critical information for the mechanistic study of the heat-treatment effects, such as hot isostatic pressing (HIP), annealing, cold rolling, and forging, on microstructures and mechanical properties of HEA systems. This research program have a transformative impact on the research, development, and applications of HEAs. The goal is accomplished by utilizing the strength at The University of Tennessee (UT)'s mechanical behavior and failure analysis of advanced structural alloys, and materials processing. UT is well equipped with the synthesis equipment, mechanical-testing instruments, and microstructural-characterization tools. The synergetic efforts facilitate the effectiveness and success of the proposal research. Broader impacts The current research on fatigue-fracture and environmentally-assisted behavior of HEAs enriches the research and teaching efforts on advanced materials at UT. The presentations at professional conferences and the publications in academic journals achieve the wide national and international impact. The efforts not only increase the public awareness on the fatigue-fracture and environmentally-assisted behavior of HEAs and their scientific importance, but also stimulate the interests of the student in pursuing the science, engineering, and technology fields of study.

Book Description
Written by a leading researcher in the field, this revised and updated second edition of a highly successful book provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, non-metals and composites. The author discusses the principles of cyclic deformation, crack initiation and crack growth by fatigue, covering both microscopic and continuum aspects. The book begins with discussions of cyclic deformation and fatigue crack initiation in monocrystalline and polycrystalline ductile alloys as well as in brittle and semi-/non-crystalline solids. Total life and damage-tolerant approaches are then introduced in metals, non-metals and composites followed by more advanced topics. The book includes an extensive bibliography and a problem set for each chapter, together with worked-out example problems and case studies. This will be an important reference for anyone studying fracture and fatigue in materials science and engineering, mechanical, civil, nuclear and aerospace engineering, and biomechanics.

Book Description
This special-topic book consists of a collection of technical papers assembled under the rubric of Advances in Understanding the Fatigue Behavior of Materials. The focus of Fatigue Behavior of Materials centers on the changes in properties that occur upon applying cyclic loads. Following its recognition and increasing importance during the latter half of the nineteenth century, this branch of study has focused upon the study and rationalization of the engineering approaches that are commonly used to design against the initiation and/or propagation of the fatigue damage which would otherwise culminate in catastrophic failure.

Book Description
Fatigue and Durability of Structural Materials explains how mechanical material behavior relates to the design of structural machine components. The major emphasis is on fatigue and failure behavior using engineering models that have been developed to predict, in advance of service, acceptable fatigue and other durability-related lifetimes. The book covers broad classes of materials used for high-performance structural applications such as aerospace components, automobiles, and power generation systems. Coverage focuses on metallic materials but also addresses unique capabilities of important nonmetals. The concepts are applied to behavior at room or ambient temperatures; a planned second volume will address behavior at higher-temperatures. The volume is a repository of the most significant contributions by the authors to the art and science of material and structural durability over the past half century. During their careers, including 40 years of direct collaboration, they have developed a host of durability models that are based on sound physical and engineering principles. Yet, the models and interpretation of behavior have a unique simplicity that is appreciated by the practicing engineer as well as the beginning student. In addition to their own pioneering work, the authors also present the work of numerous others who have provided useful results that have moved progress in these fields. This book will be of immense value to practicing mechanical and materials engineers and designers charged with producing structural components with adequate durability. The coverage is appropriate for a range of technical levels from undergraduate engineering students through material behavior researchers and model developers. It will be of interest to personnel in the automotive and off-highway vehicle manufacturing industry, the aeronautical industry, space propulsion and the power generation/conversion industry, the electric power industry, the machine tool industry, and any industry associated with the design and manufacturing of mechanical equipment subject to cyclic loads.
