  • 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 control of non-metallic inclusions in cast steel

    Creator:
    Belding, Philip Charles
    Abstract:
    Exogenous and indigenous inclusions are defined and described with respect to their origins and effects in cast steel. Means of minimizing exogenous inclusions thru prevention of their formation as well as entrapment in the mold filling system are discussed. Indigenous inclusions arise from elements normally present in steel, principally oxygen,...

  • Creep of tungsten dispersion strengthened by ZrO₂

    Creator:
    Blickensderfer, Robert
    Abstract:
    Tungsten alloys containing approximately 0.75 and 2.3 vol pct Zr0₂ were prepared by powder metallurgical methods from blends of commercial tungsten powder and ZrW₂ powder. A heat treatment of the extruded rods at 1800°C was found to produce a stable structure with a dispersion of Zr0₂ particles in the tungsten...

  • Deformation mechanism of polycrystalline and monocrystalline high purity vanadium at low temperatures

    Creator:
    Wang, Chun T.
    Abstract:
    High purity vanadium, both in the polycrystalline and monocrystalline form, was strained in tension in order to study the controlling deformation mechanism at temperatures between 77 and 293°K. The temperature and strain rate dependence of the flow stress for two grades of material, 99.99% and 99.93%, was evaluated using temperature...

  • The determination and characterization of preferred orientation and the elastic anisotropy of rolled copper sheet

    Creator:
    Wilson, Dale
    Abstract:
    Relatively simple methods are developed for obtaining discreet orientation characterization of preferred orientation from x-ray diffraction-determined pole figure data. It is demonstrated how this information, along with the single crystal elastic constants, can be used to calculate Young's modulus as a function of sheet direction. Computer programs are developed for...

  • A numerical model for predicting energy dispersion in thermal plumes issuing from large, vertical outfalls in shallow coastal water

    Creator:
    Trent, Donald S.
    Abstract:
    A theoretical study of the heat and momentum transfer resulting from a flow of power plant condenser effluent discharged vertically to shallow, quiescent coastal receiving water is presented. The complete partial differential equations governing steady, incompressible, turbulent flow driven by both initial momentum and buoyancy are solved using finite-difference techniques...

  • A portable pumping system for hydraulic excavation of commercial crab pots

    Creator:
    Chang, Terrill John
    Abstract:
    The design and testing of a portable pumping system for use in the hydraulic excavation of commercial crab pots buried by ocean sediment was undertaken. The resulting portable system retained the four major components of the pumping systems presently used by commercial fishermen: engine, pump, fire hose, and nozzle. Because...

  • On design and field evaluation of the noise control features of the Lake Oswego water treatment plant

    Creator:
    Reeder, Harry Cromwell
    Abstract:
    Concern about noise pollution has swept the country. People are conscious of their environment and are trying to preserve or to improve it. When the City of Lake Oswego selected a site for their water treatment plant, they had to assure the neighbors that it would not increase the ambient...

  • A nonlinear dynamic analysis of inextensible mooring lines

    Creator:
    Rupe, Robert Charles
    Abstract:
    For over a hundred years, analysts have been concerned with the static and dynamic behavior of flexible cables. Hanging, towing and mooring cables have been extensively examined but little work has been done in the area of the anchor deployment problem. In the anchor deployment problem, a mooring line is...
