Available in PDF, EPUB and Kindle. Book excerpt: Experimental evidence regarding pressure gradients in Bridgman anvil devices is reviewed and some new experimental data are presented. Although there are many differences in details, all the experimental evidence is found to fit a general pattern. A simple empirical relationship describing the pressure distribution is derived which is consistent with experimental observation. The experimentally determined pressure is used to estimate errors introduced into various types of anvil experiments by pressure gradients. Numerical values for the correction factors are given in graphical form for a wide range of experimental conditions. Analysis of shear experiments indicates that pressure gradients are much smaller under dynamic conditions. Analysis also shows that the peripheral sample region which is partially nonload-supporting frequently has a greater detrimental effect on anvil experiments than does the pressure gradient which exists over the central portion of the sample cell.

Download or read book Shear Strength of Twelve Grossly Deformed Metals at High Pressures and Temperatures written by Robert E. Riecker and published by . This book was released on 1967 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The shear strength of grossly deformed tungsten, germanium, nickel, beryllium, uranium, copper, gold, silver, aluminum, magnesium, bismuth, and tin was measured in an opposed anvil shear apparatus at pressures up to 150 kb at 27C, and for gold, silver, and copper to 900C. The shear data agree with independent strength measurements at low pressures, but differ significantly from high-pressure shear-strength measurements made by other investigators. The data on the noble metals also fit a simple empirical formula relating the temperature and pressure dependence of the shear strength. (Author).

Download or read book Shear Strength Polymorphism and Mechanical Behavior of Olivine Enstatite Diopside Labradorite and Pyrope Garnet written by Robert E. Riecker and published by . This book was released on 1966 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four hundred and seventeen shear and compression tests were completed on five minerals: olivine, enstatite, diopside, labradorite, and pyrope garnet. These minerals are assumed to represent the principal constituents of an upper mantle rock model. Petrographic examination and x-ray analyses indicate that the minerals deform cataclastically at low pressures and temperatures, with intragranular flow beginning at 30 kb normal pressure. Temperature enhances ductility, indicated at high pressures by x-ray line broadening on diffraction patterns and the appearance of kink bands in thin sections. Two phenomena of geophysical importance have been discovered during shear testing: (1) dehydration of less than 5 percent by volume of serpentine weakens dunite by more than 30 percent as the temperature is raised from 300C to 520C; (2) orthorhombic enstatite readily inverts to monoclinic polymorph under the influence of shear stress at all pressures and the temperatures to 920C and 50 kb. The inversion is accompanied by a small, rapid change in volume, sufficient to yield seismic energy for the production of a moderate earthquake. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The report describes the design, installation, calibration and test of one of the high temperature crystal growing furnace systems of the Solid State Sciences Laboratory of the Air Force Cambridge Research Laboratories. A number of the modifications and innovations that make this system unique are described. Pictures and diagrams of the furnace and associated apparatus and component specifications are sufficiently complete to provide substantial aid in the operation or duplication of this facility. The furnace has been operated above 2800C for short periods of time (hours) and above 2000C for extended periods (days). It has been in operation for over a year and more than 50 separate experiments have been conducted. (Author).
