An X-ray diffraction examination of alloy single crystals of Fe containing between about 14 and 23 at.% Al has revealed the existence of an intermediate temperature region in which long range ordered phases based on the stoichiometric compounds Fe3Al and FeAl coexist in equilibrium. This result is in excellent agreement with theoretical predictions which assume the Fe3Al type phase disorders by a first order transformation in alloys containing less than about 25 at.% AI. The K-state phenomenon in the Fe-Al alloys is discussed in terms of a revised segment of the Fe-Al phase diagram based on the present results. |
