摘要：

Multilayered films of Rh1-xTax (x = 25, 40, 50, 60) were prepared and irradiated by 200 keV Xe+. A Gibbs free energy diagram of the Rh-Ta system was derived that predicted the glass-forming range to be within 43-65 at.% of Ta. This agreed well with the experimental results. An interest phase transformation mechanism of Rh + Ta --> fccI + fccII --> fcc was observed and discussed. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
