Metastable Fe(Pd) Alloys Formed by Pulsed Electron Beam Melting

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, in spite 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.
