Tóm tắt

New amorphous alloys in Al-Ln (Ln=Pr, Nd, Sm or Gd) binary systems have been formed in the vicinity of 10 at% Pr and in the ranges of 8 to 12%Nd or Gd and 8 to 16%Sm by rapid solidification. Crystallization temperature, hardness, tensile strength and electrical resistivity at 293 K of the binary amorphous alloys increase with an increase of solute content from 453 to 511 K, 150 to 325 DPN, 495 to 960 MPa and 96 to 170 µΩcm, respectively. The compositional dependences are interpreted on the basis of the presumption that the attractive bonding nature between Al and Ln metals is a dominant factor.
