Book Synopsis Kinetics of Structural Relaxation in Metallic Glasses. [PdGe ; FeNiPB]. by :
Download or read book Kinetics of Structural Relaxation in Metallic Glasses. [PdGe ; FeNiPB]. written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: When a metallic glass is annealed at temperatures below the glass transition temperature its structure changes with time. This structural change is observed to have an irreversible component and a reversible component. Our work has concentrated on studying the reversible component of the structural relaxation. In this paper the reversible component is called chemical short-range order (CSRO) and the irreversible components topological short-range order (TSRO). It is believed important to determine if the spectrum of relaxation times has fine structure. Experiments have been carried out to obtain the maximum possible detail about the kinetic behavior of the CSRO changes. Also a new method of analysis of the response curve, referred to as direct spectrum analysis, has been used to resolve fine structure in the spectrum of relaxation times.
Book Synopsis Comparison of Structural Relaxation Behavior in As-Cast and Pre-Annealed Zr-Based Bulk Metallic Glasses Just Below Glass Transition by :
Download or read book Comparison of Structural Relaxation Behavior in As-Cast and Pre-Annealed Zr-Based Bulk Metallic Glasses Just Below Glass Transition written by and published by . This book was released on 2015 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, the [alpha]-relaxation of pre-annealed Zr55Cu30Ni5Al10 bulk metallic glasses (BMGs) was compared with that of as-cast Zr-based BMGs including Zr55Cu30Ni5Al10. The [alpha]-relaxation was investigated by volume relaxation. The relaxation behavior was well described by a stretched exponential relaxation function, [Phi] (t) H"exp [- (t/[tau] [alpha])[beta] [alpha]], with the isothermal relaxation time, [tau][alpha], and the Kohlrausch exponent, [beta][alpha]. The [beta][alpha] exhibited the strong temperature dependence for the pre-annealed BMG, while the weak temperature dependence was visualized for the as-cast BMG similar to the dynamic relaxation. The [tau][alpha]'s were modified by Moynihan and Narayanaswamy-Tool-Moynihan methods that reduce the difference in the thermal history of sample. Finally, as a result, the relaxation kinetics in the glass resembled that of a liquid deduced from the behavior of viscosity in the supercooled liquid.

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.
Book Synopsis Rapidly Quenched Metals by : S Steeb
Download or read book Rapidly Quenched Metals written by S Steeb and published by Elsevier. This book was released on 2012-12-02 with total page 1163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapidly Quenched Metals, Volume I covers the proceedings of the Fifth International Conference on Rapidly Quenched Metals, held in Wurzburg, Germany on September 3-7, 1984. The book focuses on amorphous and crystalline metals formed by rapid quenching from the melt. The selection first covers the scope and trends of developments in rapid solidification technology, rapid solidification, and undercooling of liquid metals by rapid quenching. Discussions focus on experimental method, powders, strip, particulate production, consolidation, and alloys and alloy systems. The text then examines the solidification of undercooled liquid alloys entrapped in solid; crystallization kinetics in undercooled droplets; and grain refinement in bulk undercooled alloys. The manuscript tackles the undercooling of niobium-germanium alloys in a 100 meter drop tube; influence of process parameters on the cooling rate of the meltspinning process; and the mechanism of ribbon formation in melt-spun copper and copper-zirconium. The formation and structure of thick sections of rapidly-solidified material by incremental deposition and production of ultrafine dispersions of rare earth oxides in Ti alloys using rapid solidification are also mentioned. The selection is a valuable reference for physicists, chemists, physical metallurgists, and engineers.
Book Synopsis Viscosity And Relaxation by : D Uhlmann
Download or read book Viscosity And Relaxation written by D Uhlmann and published by Elsevier. This book was released on 2012-12-02 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glass: Science and Technology, Volume 3: Viscosity and Relaxation provides notable developments in the field of glasses. This book contains seven chapters that specifically tackle the scientific and engineering aspects of glass viscosity, viscoelasticity, relaxation, and annealing. This book considers first the basis for the analysis of the data produced in relaxation experiments by testing a variety of mechanical models that help to define many of the viscoelastic properties and to establish relationships between them. The subsequent chapters discuss the basic information on the rheology of viscoelastic substances; the atomic transport properties and structural relaxation processes; and the technological aspects of viscosity and its dependence on temperature, stress, time, and composition. This book further explores the physical mechanisms and theories of glass annealing. Separate chapters deal with the inorganic nonmetallic, organic polymers, and metal glasses. This book will be of value to glass scientists and researchers.

Book Synopsis Supercooled Liquids, Glass Transition and Bulk Metallic Glasses: Volume 754 by : Takeshi Egami
Download or read book Supercooled Liquids, Glass Transition and Bulk Metallic Glasses: Volume 754 written by Takeshi Egami and published by . This book was released on 2003-07-16 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a renaissance in glass science brought about by the development of concepts such as fragility index and the energy landscape with megabasins. Research on bulk metallic glasses has been explosive since their advent when MRS offered its first book on the topic. In 2000, a second book broadened the scope to include supercooled liquid, bulk glassy and nanocrystalline states. This book enhances the scope to include glass transition in diverse materials such as water, silicate and polymeric melts. Bringing these threads together in an interdisciplinary manner was fruitful and offers proof that while there is much common ground, gaps between various approaches to the glassy state remain to be bridged. Subjects include: the supercooled liquid; glass formability; structural relaxation and dynamics; structure determination and modeling; processing and applications of bulk metallic glasses; mechanical properties; mechanical properties - composites; crystallization; electronic and magnetic structure and properties; and nanoparticles and nonmetallic glasses.
