Book excerpt: Metallic glasses are very promising engineering and functional materials due to their unique mechanical, chemical, and physical properties, attracting increasing attention from both scientific and industrial communities. However, their practical applications are greatly hindered due to three main problems: dimensional limit, poor tension plasticity, and difficulty in machining and shaping. Therefore, further investigation of these issues is urgently required. This book provides readers with recent achievements and developments in the properties and processing of metallic glasses, including mainly thermoplastic forming of metallic glasses (Chapter 2), atomic-level simulation of mechanical deformation of metallic glasses (Chapter 3), metallic glass matrix composites (Chapter 4), and tribo-electrochemical applications of metallic glasses (Chapters 5 and 6).

Book excerpt: 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.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glassy states are commonly observed across metallic, organic, and ceramic materials. They exhibit unique mechanical, thermal, and electronic properties. Metallic glasses are stronger than regular metals while being as pliable as plastics, but their wide-spread technological adoption is hindered by our poor understanding of their atomic ordering. Organic glasses have applications ranging from electronics to pharmaceuticals. Glasses lack long-range order, and their properties are mediated by nano-scale ordering. Experimental characterization of glassy structures is incredibly challenging due to the awesome complexity of their nanostructures and a lack of characterization techniques that can probe the local ordering and structural relaxation processes with nanometer-scale spatial resolution. Characterization techniques based on transmission electron microscopy (TEM) probe the structure and dynamics of such systems with nanometer-scale spatial resolution. Structural studies on metallic and organic glasses using 4-dimensional scanning transmission electron microscopy (4D STEM) reveal varying length scales of ordering in these systems and their impact on physical properties, at unprecedented spatial resolution. Electron correlation microscopy (ECM) analysis on time-resolved in situ thermal annealed TEM data lets us study glassy dynamics and reveals spatially heterogeneous dynamics in the bulk and at the surface of metallic glass nanowires. The techniques developed, and the mechanisms of structural ordering and relaxation dynamics revealed in these investigations, have implications on the synthesis, processing, and characterization of glassy systems with controlled thermal, electronic and mechanical properties, including growth of ultrastable metallic glass phases and molecular glasses with tunable structural anisotropy for organic electronics applications, fabrication of glassy nanostructures by superplastic forming, and control of surface crystallization.

Available in PDF, EPUB and Kindle. Book excerpt: The term "metallic glasses" is widely used to denote the amorphous alloys obtained by rapid quenching techniques. These materials are characterized by short range atom ordering without translational periodicity of the structure. Kinetic and thermodynamic metastability is one of the main characteristics generally related to metallic glasses, while their thermally induced microstructural transformations could result in deterioration or improvement of the functional properties. Due to their favorable magnetic, electrical, mechanical, and anti-corrosion properties, metallic glasses as new and attractive materials have found application in many areas of modern industries - electronics, construction industry, aerospace industry; as well as chemistry, biomedicine, and surgery.

Available in PDF, EPUB and Kindle. Book excerpt: Bulk metallic glasses (bulk amorphous alloys) constitute an exciting class of metallic materials for structural and functional use. These glass-forming metallic alloys vitrify at relatively low cooling rates (from the molten state), compared with conventional rapidly quenched metallic glasses. Owing to their exceptional resistance to crystallization, these 'easy' glass-forming alloys can be cast in bulk form with dimensions of millimeters or centimeters. The development of such alloys has opened the possibility for studies of the kinetic and thermodynamic properties of undercooled liquids. It also looks at applications for glassy metals based on the ability to fabricate three-dimensional shapes and components. It has become apparent that the development of bulk glass-forming alloys has ushered in a second generation of development in the field of amorphous metals. This book discusses the progress being made. Topics include: atomic and electronic structure; general topics in bulk metallic glasses; glass-forming ability and thermal stability; thermal stability, transport and magnetic properties and mechanical and other properties.

Available in PDF, EPUB and Kindle. Book excerpt: Metallic glasses and amorphous materials have attracted much more attention in the last two decades. A noncrystalline solid produced by continuous cooling from the liquid state is known as a glass. From the other point of view, a noncrystalline material, obtained by any other process, for example, vapor deposition or solid-state processing methods such as mechanical alloying, but not directly from the liquid state, is referred to as an amorphous material. At this moment, bulk metallic glasses (BMG) are appearing as a new class of metallic materials with unique physical and mechanical properties for structural and functional usage. Extreme values of strength, fracture toughness, magnetic properties, corrosion resistance, and other properties have been registered in BMG materials.

Available in PDF, EPUB and Kindle. Book excerpt: Amorphous Au-Ge and Ag-Ge alloy films were prepared by co-evaporation on low-temperature (15-20K) substrates under ultra-high vacuum for Ge concentrations between 20 and 40 at.%. Changes in short-range order have been observed by room-temperature electron diffraction experiments for Ge concentrations larger than 30 at.%. The d.c. electrical resistivity and the optical properties of the as-deposited amorphous metallic alloys are examined in detail as a function of composition. The Drude model with a constant relaxation time is found to reproduce the low-energy optical data satisfactorily.
