This book was released on 1962 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation was conducted to determine mechanical properties of several high performance alloys at room and elevated temperatures. The effects of temperature (up to 1900 F) and exposure (up to 1000 hours) at temperature on the tensile, compressive, bearing and shear properties were determined from measured stress-strain information in both the elastic and plastic range. The following materials were considered: 301 extra hard stainless steel; Ph157Mo(TH 1050); AM 355; Rene 41; and N-155. All material was from 0.050-inch sheet, except the material for the 1/8-inch diameter shear pins, which were fabricated from 1/4-inch plate. Heat treatment was in accordance with existing specifications for the materials, or other procedures approved by ASD to develop the optimum strength properties. Descriptions of the test specimens, equipment, and procedures are included. Test results are reported in tables and in curves showing the effects of temperature and time on the various mechanical properties.

Available in PDF, EPUB and Kindle. Book excerpt: ENGINEERING PHYSICS OF HIGH-TEMPERATURE MATERIALS Discover a comprehensive exploration of high temperature materials written by leading materials scientists In Engineering Physics of High-Temperature Materials: Metals, Ice, Rocks, and Ceramics distinguished researchers and authors Nirmal K. Sinha and Shoma Sinha deliver a rigorous and wide-ranging discussion of the behavior of different materials at high temperatures. The book discusses a variety of physical phenomena, from plate tectonics and polar sea ice to ice-age and intraglacial depression and the postglacial rebound of Earth’s crust, stress relaxation at high temperatures, and microstructure and crack-enhanced Elasto Delayed Elastic Viscous (EDEV) models. At a very high level, Engineering Physics of High-Temperature Materials (EPHTM) takes a multidisciplinary view of the behavior of materials at temperatures close to their melting point. The volume particularly focuses on a powerful model called the Elasto-Delayed-Elastic-Viscous (EDEV) model that can be used to study a variety of inorganic materials ranging from snow and ice, metals, including complex gas-turbine engine materials, as well as natural rocks and earth formations (tectonic processes). It demonstrates how knowledge gained in one field of study can have a strong impact on other fields. Engineering Physics of High-Temperature Materials will be of interest to a broad range of specialists, including earth scientists, volcanologists, cryospheric and interdisciplinary climate scientists, and solid-earth geophysicists. The book demonstrates that apparently dissimilar polycrystalline materials, including metals, alloys, ice, rocks, ceramics, and glassy materials, all behave in a surprisingly similar way at high temperatures. This similarity makes the information contained in the book valuable to all manner of physical scientists. Readers will also benefit from the inclusion of: A thorough introduction to the importance of a unified model of high temperature material behavior, including high temperature deformation and the strength of materials An exploration of the nature of crystalline substances for engineering applications, including basic materials classification, solid state materials, and general physical principles Discussions of forensic physical materialogy and test techniques and test systems Examinations of creep fundamentals, including rheology and rheological terminology, and phenomenological creep failure models Perfect for materials scientists, metallurgists, and glaciologists, Engineering Physics of High-Temperature Materials: Metals, Ice, Rocks, and Ceramics will also earn a place in the libraries of specialists in the nuclear, chemical, and aerospace industries with an interest in the physics and engineering of high-temperature materials.

Download or read book Metal Plasticity and Fatigue at High Temperature written by Denis Benasciutti and published by MDPI. This book was released on 2020-05-20 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: In several industrial fields (such as automotive, steelmaking, aerospace, and fire protection systems) metals need to withstand a combination of cyclic loadings and high temperatures. In this condition, they usually exhibit an amount—more or less pronounced—of plastic deformation, often accompanied by creep or stress-relaxation phenomena. Plastic deformation under the action of cyclic loadings may cause fatigue cracks to appear, eventually leading to failures after a few cycles. In estimating the material strength under such loading conditions, the high-temperature material behavior needs to be considered against cyclic loading and creep, the experimental strength to isothermal/non-isothermal cyclic loadings and, not least of all, the choice and experimental calibration of numerical material models and the selection of the most comprehensive design approach. This book is a series of recent scientific contributions addressing several topics in the field of experimental characterization and physical-based modeling of material behavior and design methods against high-temperature loadings, with emphasis on the correlation between microstructure and strength. Several material types are considered, from stainless steel, aluminum alloys, Ni-based superalloys, spheroidal graphite iron, and copper alloys. The quality of scientific contributions in this book can assist scholars and scientists with their research in the field of metal plasticity, creep, and low-cycle fatigue.
Download or read book The Effects of Thermal Processing on the Mechanical Properties of AA2024 2014 and 2618 Aluminum Alloys written by Xiao Li and published by . This book was released on 1993 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study determined the independent effects of various homogenization cycles and precipitation treatments on the elevated temperature workability and the final ambient temperature mechanical properties of AA2024 aluminum alloy and on the T3 tensile properties of 2014 aluminum alloy as well as T6 tensile properties of 2618 and 2618 (Curich) aluminum alloys. The elevated-temperature tensile and extrusion tests indicate that the workability of AA2024 alloy improves with elevated-temperature precipitation treatment as suggested by earlier investigations. The precipitation treatments do not appear to degrade the ambient-temperature T3 and T8 tensile properties. The time at the precipitation temperature appears to affect the T3 and T8 tensile properties in unextruded ingot, longer times especially providing both relatively high ambient-temperature strength and ductility of AA2024 alloy. The time at the standard homogenization temperature and the heat-up and cool-down rates do not dramatically affect the T3 tensile properties of unextruded ingot of AA2024 and 2014 alloys. However, long soak times at the homogenization temperature and more rapid cooling rates may improve the properties somewhat of AA2024 alloy and longer heat-up times and rapid cooling rates may slightly improve the properties of 2014 alloy. The higher standard solution temperature appears to increase both strength and ductility of 2014 alloy over lower temperatures. The homogenization temperature affects the T6 tensile properties of 2618 and 2618 (Cu-rich) alloys, a high homogenization temperature (compare to standard homogenization temperature) providing both high strength and ductility. Increased manganese and copper appears to increase the strength, but slightly decreases the ductility. The standard aging temperature and time produce higher strength but lower the ductility than lower temperatures at the same or shorter aging times in 2618 (Cu-rich) alloy.

Available in PDF, EPUB and Kindle. Book excerpt: High Temperature Structures and Materials is a compilation of the proceedings of the Third Symposium on Naval Structural Mechanics held at Columbia University in New York on January 23-25, 1963. The symposium provided a forum for discussing structural mechanics under conditions of elevated temperatures. Emphasis is placed on the various aspects of structural design for elevated temperature service. The following areas are covered: material aspects of elevated temperature design; effects of high-speed environment; thermal stress analysis; and design criteria and reliability. This book is comprised of 13 chapters and begins by assessing the temperature dependence of elastic and anelastic properties in solids, followed by a discussion on the thermo-mechanical behavior of ceramics. Subsequent chapters explore the physical aspects of creep; thermal fatigue and its relation to creep rupture and mechanical fatigue; materials aspects of the re-entry problem; and problems of heat conduction and melting. Thermal stresses in viscoelastic solids are also considered, along with creep design and aspects of reliability under conditions of elevated temperature creep and fatigue. This monograph will be a valuable resource for material physicists and mechanical and structural designers concerned with the problem of elevated temperature effects on the performance and safety of modern structures.

Available in PDF, EPUB and Kindle. Book excerpt: Apparatus has been developed to allow the compression testing of sheet materials at elevated temperatures. It includes a testing fixture, a special extensometer, and an oil-bath furnace which are described in detail. The short-time compressive properties of five high-strength aluminum alloy sheet materials have been determined at temperatures up to 300 F. after exposures ranging from 1⁄2 to 1000 hr. The materials include 24S-T, 24S-T81, 24S-T86, R301-T, and 75S-T. The effects of temperature and time on compressive yield strength are compared with those for the corresponding tensile properties and it is found that approximate values of compressive yield strength may be derived from calculations based upon the tension values. Of the materials tested, the members of the 24S-T8 series appear to offer the best possibilities for elevated-temperature service.

This book was released on 2018-03-19 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Tensile Properties of Alloy Steels at Elevated Temperatures as Determined by the "Short-Time" Method The information available on the correlation of results from short time and from flow tests is rather limited. N o conclusions that short time tests can entirely replace flow tests are warranted on the basis of available information. It is believed, however, that a large amount of valuable preliminary information can be obtained with the short time method with a great saving of time in the study and development of alloys for continuous service at elevated temperatures. In fact, since the advent of austenitic alloys for service at elevated tempera tures there is still more reason for extended flow tests, such tests to be made for even longer periods of time than heretofore. As many austenitic alloys are metastable yet sluggish in their response to ther mal treatment at temperatures in the vicinity of to F. (6000 to 700° C.) it would not seem advisable to determine their characteristics by the short-time method only. The group of materials reported upon in this paper includes both commercial alloy steels and some special alloys which had been made primarily to show the effects on the tensile properties of various alloy ing elements, such as silicon, chromium, nickel, vanadium, tungsten, molybdenum, and aluminum.
