The composition dependence of order-disorder transition temperature T c of Fe 1- c Pt c alloys ( c =0.22, 0.25, 0.28, 0.33, 0.345 and 0.36) was investigated by measuring the X-ray integrated intensity of powder diffraction at high temperature. The temperatures T c between the L1 2 -type ordered structure and disordered fcc structure were significantly different from those reported thus far. The maximum T c of the L1 2 structure was not at the composition of 25 at% Pt, but at about 33 at% Pt. It was found that the L1 2 and the L1 0 ordered phases coexisted at around 34.5 at% Pt. A new phase diagram was proposed based on the measurements.
