ANISOTROPIC MECHANICAL BEHAVIOR IN SAPPHIRE (A1203) WHISKERS

Abstract

A method of static tension testing whiskers was described which made it possible to obtain more precise data on the mechanical behavior of sapphire (A1203) whiskers at 25C. Anisotropy was detected and measured in tensile properties of a sample of near-micron size whiskers. Measured elastic moduli, whisker cross section geometry, and yield points were useful in identifying whiskers having axes corresponding to simple growth directions in sapphire; i.e. , the <0001> , <1120> , and <1100> directions.
