Abstract

Fe(Pd) surface alloys formed by either ion implanting Pd into Fe or by vapor depositing Pd on Fe have been examined after pulsed (∼70 nsec) electron beam melting. TEM and ion backscattering/channeling showed that the implanted alloys with up to 9.6 at.% Pd were bcc and epitaxial with the substrate, inspite of predictions of initial solidification to the fcc phase by the Fe-Pd phase diagram. The resolidified Pd films, however, were fcc as predicted by the diagram. The defect structures observed in these alloys are discussed.
