    Extractive Metallurgy Division - Thermodynamics of Iron-Silicate Slags: Slags Saturated With Solid Silica

    By R. Schuhmann, E. J. Michal

    Experimental measurements are reported for the oxygen pressures of iron-silicate slags in equilibrium with solid silica. CO2-CO mixtures were bubbled through the slags in silica crucibles to find equi

    Institute of Metals Division - Estimation of the Entropy of NaCl-Type Compounds

    By Larry Kaufman

    A useful method for estimating the entropy of NaCl type compounds has been developed by combining the Debye theory of specific heat with the Lindemann formula. This method pemnits calculation of the e

    Institute of Metals Division - Design for Molybdenum Wire Wound Furnace (TN)

    By T. P. Papazoglou, N. A. D. Parlee, W. C. Phelps

    PRACTICAL designs for good "home made" molybdenum furnaces are hard to find in the literature. The one described briefly below left something to be desired but was good enough to operate as a rathe

    Part X – October 1968 - Papers - Double Accommodation Kinking and Growth of {1121} Twins in Zirconium

    By R. E. Reed-Hill, W. H. Hartt, W. A. Slippy

    An unusual form of double kinking has been observed at the ends of {1121} twins in deformed zirconium. These kinks lie partly outside of the twin and partly inside. While they are undoubtedly closely

    Papers - Well Logging - Some Practical Aspects of Radioactivity Well Logging (T. P. 1923)

    By John L. P. Campbell, Warren J. Jackson

    Automatic recording of the radioactivity of the earth's formations provides a log of relative intensities that, if properly interpreted, can be applied to oil-field engineering. Production, engin
