This book was released on 2006 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study utilizes differential scanning calorimetry (DSC) to characterize the thermodynamics, kinetics and crystallization b processes of a new Pt57.3Cu14.6Ni5.3P22.8 bulk metallic glass forming alloy. The heat capacity of the alloy is measured for the crystalline, glassy, and supercooled liquid phases. This data is used to obtain thermodynamic driving forces for crystallization and quantify the thermodynamic fragility. Kinetic properties of the alloy are investigated by observing the glass transition under different heating rates. The heating rate dependence of the glass transition is then used to calculate the kinetic fragility and estimate how the material's viscosity varies with temperature. DSC is also used to observe the crystallization event at variety of temperatures and generate a Time-Temperature-Transformation (TTT) diagram for crystallization. The crystallization results and TTT diagram are compared with thermodynamic and kinetic data using classical nucleation theory, and different models for crystallization are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of an in-depth study of investigating microstructure-property relationships in bulk metallic glasses using a novel quantitative approach by which influence of the second phase features on mechanical properties can be independently and systematically analyzed. The author evaluates and optimizes the elastic and plastic deformation, as well as the overall toughness of cellular honeycombs under in-plane compression and porous heterostructures under uniaxial tension. The study reveals three major deformation zones in cellular metallic glass structures, where deformation changes from collective buckling showing non-linear elasticity to localized failure exhibiting a brittle-like deformation, and finally to global sudden failure with negligible plasticity as the length to thickness ratio of the ligaments increases. The author found that spacing and size of the pores, the pore configuration within the matrix, and the overall width of the sample determines the extent of deformation, where the optimized values are attained for pore diameter to spacing ratio of one with AB type pore stacking.

This book was released on 2018-07-31 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive and holistic study of microstrucure evoution during solidification and additive manufacturin.g Bulk metallic glasses and their composites have attracted a lot of attention lately in the scientific community owing to their excellent mechanical properties (combination of hardness, strength, and high elastic strain limit). However, they still lack toughness and tensile ductility and exhibit catastrophic failure upon tension. This can be overcome by various means, of which in situ introduction of ductile crystalline precipitates/phases during solidification proved to be the best. Various studies have been carried out in the last two decades, which explain this phenomenon. However, there is a gap on how this can be achieved in modern additive manufacturing exploiting inherent nature of process. This book aims to bridge this gap. A comprehensive and holistic study is presented, documenting the step-by-step evolution of these materials since their inception till date, explaining the development of toughness in them by modeling and simulation of microstructure evolution during solidification and additive manufacturing.

Download or read book Fast Scanning Calorimetry written by Christoph Schick and published by Springer. This book was released on 2016-06-28 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decades, the scan rate range of calorimeters has been extended tremendously at the high end, from approximately 10 up to 10 000 000 °C/s and more. The combination of various calorimeters and the newly-developed Fast Scanning Calorimeters (FSC) now span 11 orders of magnitude, by which many processes can be mimicked according to the time scale(s) of chemical and physical transitions occurring during cooling, heating and isothermal stays in case heat is exchanged. This not only opens new areas of research on polymers, metals, pharmaceuticals and all kinds of substances with respect to glass transition, crystallization and melting phenomena, it also enables in-depth study of metastability and reorganization of samples on an 1 to 1000 ng scale. In addition, FSC will become a crucial tool for understanding and optimization of processing methods at high speeds like injection molding. The book resembles the state-of-the art in Thermal Analysis & Calorimetry and is an excellent starting point for both experts and newcomers in the field.

Download or read book Differential Scanning Calorimetry written by G.W.H. Höhne and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differential Scanning Calorimetry (DSC) is a well established measuring method which is used on a large scale in different areas of research, development, and quality inspection and testing. Over a large temperature range, thermal effects can be quickly identified and the relevant temperature and the characteristic caloric values determined using substance quantities in the mg range. Measurement values obtained by DSC allow heat capacity, heat of transition, kinetic data, purity and glass transition to be determined. DSC curves serve to identify substances, to set up phase diagrams and to determine degrees of crystallinity. This book provides, for the first time, an overall description of the most impor tant applications of Differential Scanning Calorimetry. Prerequisites for reliable measurement results, optimum evaluation of the measurement curves and esti mation of the uncertainties of measurement are, however, the knowledge of the theoretical bases of DSC, a precise calibration of the calorimeter and the correct analysis of the measurement curve. The largest part of this book deals with these basic aspects: The theory of DSC is discussed for both heat flux and power compensated instruments; temperature calibration and caloric calibration are described on the basis of thermodynamic principles. Desmearing of the measurement curve in different ways is presented as a method for evaluating the curves of fast transitions.

Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) is one of the manufacturing processes that warrants the attention of industrialists, researchers, and scientists. AM has the ability to fabricate materials to produce parts with complex shapes without any theoretical restrictions combined with added functionalities. Selective laser melting (SLM), also known as laser-based powder bed processing (LPBF), is one of the main AM process that can be used to fabricate wide variety of materials that are Al-, Ti-, Fe-, Ni-, Co-, W-, Ag-, and Au-based, etc. However, several challenges need to be addressed systematically, such as development of new materials that suit the SLM process conditions so the process capabilities can be fully used to produce new properties in these materials. Other issues in the field are the lack of microstructure-property correlations, premature failure, etc. Accordingly, this Special Issue (book) focuses mainly on the microstructure-correlation in three different alloys: AlSi10Mg, Ti6Al4V, and 304L stainless steel, where six articles are presented. Hence, this Special Issue outlines microstructure-property correlations in the SLM processed materials and provides a value addition to the field of AM.
