A STUDY OF THE GROWTH MECHANISMS OF ALLOY FILAMENTARY CRYSTALS (WHISKERS) GROWN FROM THE SOLID.
Abstract
Research was conducted in an effort to determine the mechanisms of atom transport responsible for the growth of filamentary crystals (whiskers) from the solid metal. To this end, whiskers have been grown from single phase, binary alloys of indium-tin and indium-lead. Attempts have been made to detect any difference in composition between the whisker and the base alloy from which it was grown. Such a change in composition would suggest a diffusion mechanism of atom transport, whereas the absence of a change would support a mechanism involving the cooperative, repetitive movement of dislocations. Two methods have been used to study the composition of the whiskers. These are X-ray diffraction and electron probe microanalysis. Present work is directed toward overcoming some of the difficulties in making the necessarily precise analysis of the whiskers, which are only of the order of 10 to the minus 9th power grams.
