Equipment and techniques employed in ultrahigh-pressure-compression treatment of polymeric materials are described. Results of exploratory studies with several organic polymers, semiorganic compounds, and several chemical compounds are presented and discussed with respect to similar or related studies found in the literature. Physical and structural changes were found as a result of compression treatment on different materials. Although generically related materials appeared to have somewhat similar compression behavior, no general compression effect was observed.

This report deals with the deleterious effects of hydrogen gas on steel at elevated temperatures and/or pressures. Hydrogen attack on steels is manifest as decarburization, intergranular fissuring, or blistering. These conditions result in lowered tensile strength, ductility, and impact strength. The reaction of hydrogen with iron carbide to form methane is probably the most important chemical reaction involved in the attack on steel by hydrogen. Attack of steel at elevated temperatures and pressures is limited or prevented by the following measures: (1) use of steel alloyed with strong carbide-forming elements, (2) use of liners of resistant alloy steels, and (3) substitution of resistant nonferrous alloys.

High Temperature Coatings, Second Edition, demonstrates how to counteract the thermal effects of rapid corrosion and degradation of exposed materials and equipment that can occur under high operating temperatures. This is the first true practical guide on the use of thermally protective coatings for high-temperature applications, including the latest developments in materials used for protective coatings. It covers the make-up and behavior of such materials under thermal stress and the methods used for applying them to specific types of substrates, as well as invaluable advice on inspection and repair of existing thermal coatings. With his long experience in the aerospace gas turbine industry, the author has compiled the very latest in coating materials and coating technologies, as well as hard-to-find guidance on maintaining and repairing thermal coatings, including appropriate inspection protocols. The book is supplemented with the latest reference information and additional support to help readers find more application- and industry-type coatings specifications and uses. - Offers an overview of the underlying fundamental concepts of thermally-protective coatings, including thermodynamics, energy kinetics, crystallography and equilibrium phases - Covers essential chemistry and physics of underlying substrates, including steels, nickel-iron alloys, nickel-cobalt alloys and titanium alloys - Provides detailed guidance on a wide variety of coating types, including those used against high temperature corrosion and oxidative degradation and thermal barrier coatings

In many respects, the science of materials has only fully utilized two of its three fundamental tools - the variables of temperature and chemical composition. Pressure, the third fundamental variable altering materials, is in many ways the most remarkable, as it spans some 60 orders of magnitude in the universe. High-pressure science has experienced tremendous growth, particularly in the last few years. With recent developments in static and dynamic compression techniques, extreme pressure and temperature conditions can now be produced and carefully controlled over a wide range. Moreover, a new generation of analytical probes, many based on third-generation synchrotron radiation sources, have been developed and can now be applied for accurate determination of the structural, dynamical, and electronic properties of matter under extreme conditions. Finally, developments in computational techniques and advances in fundamental theory tested against bountiful new experimental results are both deepening our understanding of materials as a whole and guiding subsequent experimental work with new predictions. It was for this reason that this course on high-pressure science was held at the International School of Physics "Enrico Fermi" School in July 2001. Though presented in a physics forum, the title “High-Pressure Phenomena” was chosen to reflect the broad scope of the field and the diversity of recent findings. Indeed, the field spans fundamental physics and chemistry, materials science and technology, the geosciences, planetary science and astrophysics, as well as biology. The highly interdisciplinary character of the field was central to the organization of the school, though the sheer breadth of the field meant that many topics could be treated in only a cursory fashion while others were examined more in depth. The aim of the school was to present the state-of-the-art in techniques used in modern high-pressure research, highlighting those topics where applications of these techniques are currently having a major impact.

In the first book dedicated to this rapidly expanding research area, Mechanical Behaviour of Metal-Organic Framework Materials, provides a convenient introduction to how chemistry determines structure-mechanical property relationships and functional performance. Much of the research efforts in metal-organic framework (MOF) and hybrid framework materials focus on synthesis and adsorption related properties. But practical applications of MOFs require a precise understanding of mechanical properties and knowledge of structure-property relationships, to ensure robustness in device manufacturing and mechanical resilience for long-term performance. Readers will learn through key experimental and theoretical techniques for studying MOF mechanical properties including elastic and plastic behaviour, framework dynamics, high-pressure response, rate effects, anomalous mechanical behaviour and failure mechanisms. Edited by a pioneer of the field and with contributions by leading researchers developing the new science of “MOF Mechanics”, this book is suitable for both students and researchers who are new to the field.
