| 中文摘要 | Highly pure (99.9%) copper, tin and phosphorus powders of 250 mesh were thoroughly mixed to obtain the required ternary Cu86-xSnxP14 (x=2-15) alloy compositions. These mixtures were milled in a planetary ball mill. The powder samples at different intervals of milling were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). It has been found that a powder mixture of Cu84Sn2P14 amorphized after 28 h of mechanical alloying, but still some crystalline phase could be seen. When the period of milling was greater than 28 h, the intensity of thr crystalline Bragg reflexes increased with further milling. The period of complete amorphization for Cu86-xSnxP14, X=4, 5, 8 and 10 an 28, 20, 12 and 32 h, respectively. However, no typical amorphous phase was detected for the Cu71Sn15P14 mixture powders. The results show that the amorphization tendency increases first then decreases with increase of tin content, but no amorphous phase forms after the content of tin is greater than 15 wt%. The glass forming composition range in this alloy system is 4-10 wt% Sn. The amorphous forming ability for the ternary system is explained by the formation theory of amorphous alloys by one of the present authors. The formation enthalpies of the system are also calculated using Miedema's model, in order to explain the glass forming composition range. (C) 1999 Elsevier Science S.A. All rights reserved. |
