摘要：

The ion beam assisted deposition (IBAD) technique is utilized to study amorphization in Fe-Nb binary metal systems. The amorphous range covers a Nb fraction of approximately 34-60 at.%. The Fe-rich and Nb-rich supersaturated solid solutions of the bcc phase were obtained in Fe66Nb34 and Fe31Nb69 films, respectively In the Fe66Nb34 films. the 'amorphous --> amorphous + bcc --> bcc' evolution with increased ion beam energy front 2 to 8 keV is observed accompanying changes of film morphology. The phase formation in the IBAD process is determined by both thermodynamic and kinetic factors. (C) 2002 Elsevier Science B.V. All rights reserved.
