Mechanical Properties of Materials at Low Temperatures by D. Wigley Pdf

In writing this monograph, the aim has been to consider the mechanical properties of the wide range of materials now available in such a way as to start with the fundamental nature of these properties and to follow the discussion through to the point at which the reader is able to comprehend the significance or otherwise of the large amounts of data now available in design manuals and other compilations. In short, it is hoped that this volume will be used as a companion to these data compilations and as an aid to their interpretation. In attempting to cover such a wide field, a large degree of selection has been necessary, as complete volumes have been written on topics which here have had to be covered in a few pages or less. It is inevitable that not everyone will agree with the choice made, especially if it is his own subject which has been discussed rather briefly, and the author accepts full res ponsibility for the selection made. The book is written at a level which should be easily followed by a university graduate in science or engineer ing, although, if his background has not included a course in materials science, some groundwork may be lacking.

Nonmetallic Materials and Composites at Low Temperatures by A. F. Clark,Richard Reed,Gunther Hartwig Pdf

Cryogenics is an emerging technology filled with promises. Many cryogenic systems demand the use of nonmetallics and composites for adequate or increased performance. Thermal and electrical insulations, potting for superconducting magnets' mechanical sta bility, and composite structures appear to be some of the most significant applications. Research on nonmetallics at cryogenic temperatures has not progressed to the degree of research on metals. Nor can room temperature research be extrapolated to low tempera tures; most polymers undergo a phase transformation to the glassy state below room temperature. Research by producers, for the most part, has not been prac tical, because, except for LNG applications, the market for large material sales is not imminent. There are, however, many government stimulated developmental programs. Research on nonmetallics thus is dictated by development project needs, which require studies orien ted toward prototype hardware and specific objectives. As a result, research continuity suffers. Under these conditions, periodic topical conferences on this subject are needed. Industry and uni versity studies must be encouraged. Designers and project research material specialists need to exchange experiences and data. Low temperature-oriented research groups, such as the National Bureau of Standards and the Institute for Technical Physics - Karlsruhe, must contribute by assisting with fundamentals, interpreting proj ect data, and contributing to project programs through their materials research.

Austenitic Steels at Low Temperatures by T. Horiuchi,R. P. Reed Pdf

The need for alternate energy sources has led to the develop ment of prototype fusion and MHD reactors. Both possible energy systems in current designs usually require the use of magnetic fields for plasma confinement and concentration. For the creation and maintenance of large 5 to 15 tesla magnetic fields, supercon ducting magnets appear more economical. But the high magnetic fields create large forces, and the complexities of the conceptual reactors create severe space restrictions. The combination of re quirements, plus the desire to keep construction costs at a mini mum, has created a need for stronger structural alloys for service at liquid helium temperature (4 K). The complexity of the required structures requires that these alloys be weldable. Furthermore, since the plasma is influenced by magnetic fields and since magnet ic forces from the use of ferromagnetic materials in many configur ations may be additive, the best structural alloy for most applica tions should be nonmagnetic. These requirements have led to consideration of higher strength austenitic steels. Strength increases at low temperatures are achieved by the addition of nitrogen. The stability of the austenitic structure is retained by adding manganese instead of nickel, which is more expensive. Research to develop these higher strength austenitic steels is in process, primarily in Japan and the United States.

Thermal Properties of Solids at Room and Cryogenic Temperatures by Guglielmo Ventura,Mauro Perfetti Pdf

The minimum temperature in the natural universe is 2.7 K. Laboratory refrigerators can reach temperatures in the microkelvin range. Modern industrial refrigerators cool foods at 200 K, whereas space mission payloads must be capable of working at temperatures as low as 20 K. Superconducting magnets used for NMR work at 4.2 K. Hence the properties of materials must be accurately known also at cryogenic temperatures. This book provides a guide for engineers, physicists, chemists, technicians who wish to approach the field of low-temperature material properties. The focus is on the thermal properties and a large spectrum of experimental cases is reported. The book presents updated tables of low-temperature data on materials and a thorough bibliography supplements any further research. Key Features include: ° Detailed technical description of experiments ° Description of the newest cryogenic apparatus ° Offers data on cryogenic properties of the latest new materials ° Current reference review

Mechanical Properties of Metals at Low Temperatures by U. S. National Bureau of Standards Pdf

Excerpt from Mechanical Properties of Metals at Low Temperatures: Proceedings of the Nbs Semicentennial Symposium on Mechanical Properties of Metals at Low Temperatures, Held at the Nbs on May 14 and 15, 1951 A brief account is given of work in Europe since 1940 on the mechanical properties of metals at low temperatures. Elasticity and plasticity are dealt with, and the development of brittleness at low temperatures is discussed in relation to brittle fracture in mild steel, the behavior of heat-treated alloy steels at temperatures prevailing in the stratosphere, and the reliability of austenitic steels at liquid-air temperature. The properties at low temperatures of pure alloys of iron made at the National Physical Laboratory are described, and it is shown that some alloying additions exert influences on the rupture strength that are independent of their influence on the resistance to plastic deformation.

Cryogenics and Measurement of Properties of Solids at Low Temperatures by R. Srinivasan,A.K. Raychaudhuri,S. Kasthurirengan Pdf

Low temperature research has become fairly widespread in the country after the availability of closed cycle refrigerators. It is opportune to write a book for students and researchers in India on production of low temperatures and techniques for the measurement of physical properties of materials at such temperatures. This book is an effort in this direction. The first part of the book discusses methods for producing temperatures down to 1.8 K. There is a fairly extensive discussion on different types of closed cycle refrigerators. The behaviour of properties of materials relevant in Cryogenics is dealt with in some detail. Useful tips on construction of cryostats are given. Thermometry is discussed extensively. The second part of the book deals with digital measuring techniques. Details of experimental methods for measuring thermal and electrical properties, point contact tunneling, scanning probe microscopy, and noise at low temperatures are discussed. This part of the book is born out of the rich personal experience in such measurements of one of the authors (AKR). There is an appendix on vacuum techniques. The book can be used for teaching an elective course in Low Temperature Physics at the M.Sc. level. It will be useful for researchers in Low Temperature Physics.

Low-Temperature Properties of Polymers by I. Perepechko Pdf

Low-Temperature Properties of Polymers systematizes the available materials on polymers. This book also describes the main trends in the investigation of interrelated properties of polymers, such as thermal (heat capacity, thermal conductivity, and thermal expansion), acoustical, dielectric, and viscoelastic, which maintain the physical properties of polymers at low temperatures. Comprised of nine chapters, this book first covers heat capacity of polymers at low temperature, and then tackles thermal conductivity of polymers at low temperatures. Chapter 3 discusses thermal expansion of polymers at low temperatures, and Chapter 4 tackles electrical properties of polymers at low temperatures. The fifth chapter covers nuclear magnetic resonance in polymers at low temperature, while the succeeding chapter encompasses dynamic mechanical properties of polymers at low temperatures. Chapter 7 concerns itself with the acoustical properties of polymers at low temperatures, while the succeeding chapter covers viscoelastic parameters of polymers at low temperatures. The closing chapter covers how to determine the thermophysical characteristics of polymers by acoustic measurement at helium temperature. This book will be of great interest to researchers or professionals whose line of work involves the manipulation and understanding of the properties of polymers.
