A study was made of the long-range order parameter for the Fe/sub 3/Al ordered phase in the binary 13.9- and 16-Alfenol alloys. A single crystal of each composition was grown by the strain-anneal technique and slow cooled from 700 to 100 deg C at the rate of 5 deg /hr. The integrated intensities of three superlattice reflections for each crystal were determined by x-ray diffraction studies. Subsequently, the perfectly ordered crystals were isothermally annealed to produce an equilibrium degree of order corresponding to a constant resistivity conditlon and then rapidly quenched in an iced brine solution. The integrated intensities of the superlattice reflections were then determined as before. By repeating the procedure, a curve of the equilibrium value of long-range order parameter as a function of temperatare was obtained for each alloy. (M.C.G.)
