Martensitic phase transition in an aged Fe-Pd-Rh alloy was studied using transmission electron microscopy (TEM) and x-ray diffraction. Both TEM and x-ray diffraction reveal the appearance of an intermediate structure between the fcc→L 10 martensitic transformation. The intermediate phase, denoted L 1m, has a monoclinic structure with lattice parameters of a=3.193 Å, b=3.684 Å, c=3.141 Å, and Β=92.042°, and the normal L 10 martensitic phase has an ordered structure with lattice parameters of a=3.876 Å, c=3.684 Å, and ca=0.950, as confirmed by TEM and x-ray diffraction.
