Quenching is one of the most fundamentally complex processes in the heat treatment of metals, and it is something on which mechanical properties and distortion of engineering components depend. With chapters written by the most respected international experts in the field, Quenching Theory and Technology, Second Edition presents the most authoritative, exhaustive, and recent findings in this vital area. Understanding and control of quenching and quenchants is a critical constant in all well established and emerging heat treatment process technology. The collection of up-to-date knowledge in this book is the latest outcome from continuing formal and informal discussions by experts within the framework of the International Federation for Heat Treatment and Surface Engineering (IFHTSE). It covers topics including: Thermo-and fluid dynamic principles of heat transfer during cooling Wetting kinematics Residual stresses after cooling Computer modeling and prediction of microstructure transformation Hardness distribution Stress-strain and distortion With revised and updated content from the first edition, this book adds coverage of important technological developments. Although the primary focus continues to be on the quenching of steel, it also details quenching of aluminum and titanium alloys, quench severity of selected vegetable oils, gas quenching, intensive quenching, and simulation of quenching. Presenting the most recent findings in this area, this essential piece of literature is a substantial contribution to the general field of the thermal processing of metals. It is useful not only for specialists in heat treatment practice, but also those in higher education or numerous specialized courses and seminars worldwide.

With all chapters either revised (in some cases, completely) or expanded to account for new developments, this book sets itself apart by approaching hydraulic fluids as a component of a system and focusing on key technological aspects. Written by experts from around the world, the handbook covers all major classes of hydraulic fluids in detail, delving into chemistry, design, fluid maintenance and selection, and other key concepts. It also offers a rigorous overview of hydraulic fluid technology and evaluates the ecological benefits of water and its use as an important alternative technology. This complete overview discusses pumps and motors, valves, and reservoir design, as well as fluid properties and associated topics. These include air entrainment, modulus, lubrication and wear assessment by bench and pump testing, biodegradability, and fire resistance. Contributors also present particularly important material on biodegradable fluids and the use of water as a hydraulic fluid. As the foremost resource on the design, selection, and testing of hydraulic systems and fluids used in engineering applications, this book contains new illustrations, data tables, and practical examples, all updated with essential information on the latest methods. To streamline presentation, relevant content from the first edition has been integrated into this new version, where appropriate.

Polymers are the only material that can act as matrices for the incorporation of the widest range of ceramics, nanotubes, nanoparticles, as well as a variety of short and continuous fibres, to create new building and structural materials. Polymer science and technology is a fast growing and dynamic area of study. With this in mind, the author has followed a multidisciplinary approach covering major contemporary advancements in the subject. Largely self-contained, the book includes all essential aspects of the topic such as: polymer nanocomposites, electrospinning, and polymers in electronic applications. It offers extensive guidance on fly-ash-based polymer composites, conducting polymers, shape memory polymers, and thermoset polymer nanocomposites. There is also a review chapter on thermoplastic elastomers based on block copolymers and dynamically cured rubber-plastic blends. Ferroelectric polymer nanocomposites, polymer-based dielectrics, organic field effect transistors, super hydrophobic polymers, and biopolymers are also extensively covered. The content has been classified into six sections of polymer materials and technology: novel polymer composites, nano polymer technology, micro-macro-nano testing and characterization of polymers, speciality polymers, bio-based and biocompatible polymer materials, and new polymer applications. The book is aimed specifically at graduate students and researchers engaged in the study of polymer science and engineering and generically at those studying mechanical engineering, chemical engineering, materials science, and engineering, as well as related industry professionals.

Heat treatment of metallic alloys constitutes an important step within the production process. The heat treatment process itself is considered as a cycle of heating the workpieces to a predetermined temperature, keeping them at this temperature for the time period required, and cooling them to room temperature in an appropriate way. The process of heating and keeping workpieces at the required temperature is now adays weil mastered and mostly automatized. The process of cooling or quenching which determines actually the resulting properties, is handicapped with many physical and technical uncertainties. Good results can already be obtained predominantly by using empirically based practice. But increased demands on the properties of the pro ducts as weIl as demands on safety and environment conditions of the quenching media require efforts to investigate the details of the quenching process and to transfer the results of the research to practical application. Advances in the knowledge about quenching processes have been achieved by modem applied thermodynamics especially by the heat and mass transfer researches; further the application of computer technology was helpful to new approaches in quenching pro cesses. Special emphases has been given to: - The theory of heat transfer and heat exchange intensification during quenching - Wetting kinematics - Residual stresses after quenching - Determination of the quenching intensity - Prediction of microstructural transformation and hardness distribution after quenching, the latter with some limitations.
