Book Description
In this book, advanced steel technologies mainly developed at the National Institute for Materials Science (NIMS), Japan, for structure control, mechanical properties, and the related mechanisms are introduced and discussed. NIMS has long worked on developing advanced steel techniques, namely, producing advanced steels by using only simple alloying elements such as carbon, manganese, and silicon, and also by utilizing steel scrap. The hope is that this approach will lead to a technology of a so-called steel-to-steel recycling process, with the ultimate goal of a recycling process such as an automotive-steel-to-automotive-steel recycling process to take the place of the current cascade-type recycling system. The main idea is to utilize ultra-grain refining structures and hetero structures as well as martensite structures. In particular, the focus of this book is on tensile strength and toughness of advanced steels from both the fundamental and engineering points of view. Fundamentally, a unique approach to analysis is taken, based on fracture surface energy as effective grain size is employed to better understand the mechanism of property improvement. From the engineering point of view, in fracture toughness such factors as crack tip opening displacement (CTOD) of advanced steels are evaluated in comparison with those of conventional steels.

Book Description
Advances in Research on the Strength and Fracture of Materials: Volume 3Bs—Applications and Non-Metals contains the proceedings of the Fourth International Conference on Fracture, held at the University of Waterloo, Canada, in June 1977. The papers review the state of the art with respect to testing of fracture in a wide range of non-metals such as ceramics, glass, composites, polymers, biomaterials, and concrete. This volume is divided into five sections and opens by discussing the role of acoustic emission in fracture toughness testing and the relation between static and dynamic fracture toughness of structural steels. The reader is then introduced to methods for determining stress-intensity factors of simplified geometries of structural parts; stress analysis of pressure vessels by thermal shock; the fracture toughness of constructional steels in cyclic loading; and fracture processes and fracture toughness in powder forged steels. The remaining chapters explore the influence of low-cycle damage on fracture toughness; fracture of structural alloys at temperatures approaching absolute zero; fracture mechanisms in Si-Al-O-N ceramics; propagation and bifurcation of cracks in quartz; and the effect of pressure and environment on the fracture and yield of polymers. This monograph will be a useful resource for metallurgists, materials scientists, and structural and mechanical engineers.

Book Description
The Leeds-Lyon symposia have well established themselves in the tribological calendar. Industrial progress requires a better understanding of interfacial phenomena than now exists and it is exciting to see that the topics addressed in these proceedings volumes are at the forefront of progress in tribological research. These proceedings contain 61 papers written by authors from all over the world, covering the entire spectrum of wear particles. Of particular interest is the detailed consideration of a wide range of particle formations and detachments, as well as a close look at the physics and chemistry of the wear of mechanisms, together with other in-depth state-of-the-art analytical contributions.

Book Description
This collection commemorates the occasion of the honorary symposium that celebrated the 75th birthday and lifelong contributions of Professor K.L. Murty. The topics cover the present status and recent advances in research areas in which he made seminal contributions. The volume includes articles on a variety of topics such as high-temperature deformation behaviors of materials (elevated temperature creep, tensile, fatigue, superplasticity) and their micromechanistic interpretation, understanding mechanical behavior of HCP metals/alloys using crystallographic texture, radiation effects on deformation and creep of materials, mechanical behavior of nanostructured materials, fracture and fracture mechanisms, development and application of small-volume mechanical testing techniques, and general structure-property correlations.
