X-RAY DIFFRACTION STUDY OF IMPERFECTIONS IN RHENIUM.

Abstract

An analysis was made of the broadening of the powder pattern peaks from rhenium powders exhibiting different strength properties in the green compacts and from deformed rhenium sintered sheet. The primary source of the line broadening was the small particle size of the crystallites; broadening attributed to lattice distortions was small or negligible. Evidence was found for growth faults on the (002) planes in the samples studied, and most significantly in the powder of the low green strength briquet (one fault every 100 (002) planes) and in the deformed sheet rhenium.
