  • Studies of the radiance of metal grinding sparks

    Creator:
    Kelley, John E.
    Abstract:
    A method for measuring the spark-shower radiance of metals when abraded on an abrasive grinding wheel was developed for evaluating their sparking tendency. One hundred metals were tested and rated relative to commercially pure iron. The radiance was measured in units of energy per solid angle per area of the...

  • The effect of typical production variables on the strength of high purity commercial tantalum sheet

    Creator:
    Findley, Lee Gordon
    Abstract:
    The erratic behavior of the room temperature yield strength of high purity commercial tantalum sheet was studied. Critical factors in the production process were postulated and then investigated to determine their effects on strength properties. Chemical composition was found to be the most important factor contributing to the strength; thermomechanical...

  • The effect of alpha phase morphology on the impact energy of commercial purity titanium

    Creator:
    York, James Michael
    Abstract:
    Samples of commercial purity titanium were heat treated above the beta transformation temperature and within the two phase alpha-beta phase field, followed by cooling at varying rates. Testing of the samples in tension and by instrumented impact indicated that some strengthening could be imparted by these heat treatments, although at...

  • Indentation hardness of Douglas fir and Western hemlock lumber related to density

    Creator:
    Corder, Stanley E.
    Abstract:
    Indentation hardness tests were made on sections of 211 pieces of Douglas fir and 208 pieces of Western hemlock at a moisture content of about 11 percent. Specific gravity and visual-density evaluations were also determined. Correlation coefficients for linear regression of density, as measured by specific gravity, on average standard...
