Abstract
A variety of attritor ball milled Fe and Fe alloy powders, processed i n an argon or a nitrogen environment, were studied using X-ray diffrac tion techniques. Broadened XRD spectra were obtained due to severe pla stic deformation during ball milling. The broadening was non-uniform, displaying a systematic deviation from the average, with the (310) ref lection peak being the broadest, and the (222) reflection peak being t he sharpest. The systematic variation in broadening is interpreted as a tetragonal distortion. The tendency towards a tetragonal distortion occurred in all ball-milled samples. (C) 1998 Acta Metallurgica Inc.
