Abstract
A new consideration in the growth mechanism of whiskers is examined. The heat flow due to the shape of the crystal and the thermodynamics of the growth reaction is believed to be an important factor in the unidirectional growth observed in whiskers. A computer program was formulated to model the heat flow as well as a method to calculate the time necessary for the temperature changes to occur. It was found that there is substantial reason to believe the whisker tip is significantly cooler than the sides. This phenomenon is referred to as the cold tip mechanism which provides a preferential growth site for reaction at the tip.

    The growth of iron whiskers by the high temperature reduction of ferrous halide salts 

    Jaget, Charles William (Monterey, Calif. : Naval Postgraduate School, 1972-12);
    The growth mechanism of iron whiskers produced by the hydrogen reduction of iron halide salts was investigated by the variation of a number of parameters. The observations are correlated with current theories and with ...

    Current density limitations in a fast-pulsed high-voltage vacuum diode 

    Welsh, David S. (Monterey, California. Naval Postgraduate School, 1992-06);
    An investigation into the limitations on the enhanced field-emitted current density in a fast-pulsed (rise-time = ns), high voltage (> 106 V), 1-inch vacuum diode was conducted using a computer simulation based on the ...

    Investigation of onset of plasma formation at anode of fast-pulsed high-voltage vacuum diode 

    Willis, Gregory (Monterey, California. Naval Postgraduate School, 1993-03);
    The mechanism by which plasma forms in a fast pulsed high vacuum diode has been greatly studied. For the most part, efforts have been concentrated on plasma formation at the cathode. Recently, investigators improved the ...
