The topics discussed in this book focus on fundamental problems concerning the structural relaxation of amorphous metallic alloys, above all the possibility of studying it on the basis of viscous flow behavior and its relation to rheological anomalies, such as bend stress relaxation, thermal expansion, specific heat, density changes, and crystallization. Most relaxation studies deal with the relaxation changes of a single definite material property, and not with a wider spectrum of physical properties integrated into a common framework. This book shows that it is possible to describe these property changes on the basis of a more comprehensive theoretical understanding of their mechanism.

Reflecting the fast pace of research in the field, the Second Edition of Bulk Metallic Glasses has been thoroughly updated and remains essential reading on the subject. It incorporates major advances in glass forming ability, corrosion behavior, and mechanical properties. Several of the newly proposed criteria to predict the glass-forming ability of alloys have been discussed. All other areas covered in this book have been updated, with special emphasis on topics where significant advances have occurred. These include processing of hierarchical surface structures and synthesis of nanophase composites using the chemical behavior of bulk metallic glasses and the development of novel bulk metallic glasses with high-strength and high-ductility and superelastic behavior. New topics such as high-entropy bulk metallic glasses, nanoporous alloys, novel nanocrystalline alloys, and soft magnetic glassy alloys with high saturation magnetization have also been discussed. Novel applications, such as metallic glassy screw bolts, surface coatings, hyperthermia glasses, ultra-thin mirrors and pressure sensors, mobile phone casing, and degradable biomedical materials, are described. Authored by the world’s foremost experts on bulk metallic glasses, this new edition endures as an indispensable reference and continues to be a one-stop resource on all aspects of bulk metallic glasses.

Covers: structure of metallic glass alloys; theory of magnetism in noncrystalline solids; electronic structure of metallic glasses; magnetism in transition metal base amorphous alloys; application of metallic glasses in low-frequency magnetic devices; magnetic material properties and applications of metallic glasses in electronic devices; rare-earth transition metal base alloys; corrosion properties of amorphous alloys.

Amorphous Metals and Semiconductors contains the proceedings of an international workshop held at Coronado, California, USA on May 12-18, 1985. Organized into five parts, this book first looks into the historical perspective on semiconductors and metals. This book then explains the glass formation, magnetic glasses, and amorphous semiconductors. The mechanical and chemical properties of these materials are also given.

The discovery of bulk metallic glasses has led to a large increase in the industrial importance of amorphous metals, and this is expected to continue. This book is the first to describe the theoretical physics of amorphous metals, including the important theoretical development of the last 20 years. The renowned authors stress the universal aspects in their description of the phonon or magnon low-energy excitations in the amorphous metals, e.g. concerning the remarkable consequences of the properties of these excitations for the thermodynamics at low and intermediate temperatures. Tunneling excitations - another universal aspect of amorphous systems and responsible for many of their properties - is also intensively treated. Although the book is focused on analytical approaches, it also describes the numerical calculation of the atomic structure, the electronic excitations, and the itinerant magnetic properties of amorphous metallic alloys, while considering modern applications. While both theorists and experimentalist interested in amorphous metals will profit from this book, it will also be useful supplementary reading in courses on solid-state physics and material sciences.
