| 摘 要： | 本文利用静高压熔态淬火方法，首次对Al4Mn合金形成准晶的压力条件及其热稳定性进行了研究，发现在0.95 GPa到4.45 GPa的范围内，以102 K/s冷却速率淬火的Al4Mn合金，在不同压力下形成不同结构的准晶，利用非晶动力学理论及其结果进行了初步解释。

| Abstract: | The condition of the formation of quasierystal AI,Mn and Al6Cr under high static pressure has been investigated for the first time, 1-phase and T-phase have been observed in electron diffraction experiment. The structures of Al4 Mn quenched ai aboul 100K/s are different under various pressures from 0.95 to 4. 45GPa. The phase transition from l-phase and T-phase 10 crystal phase has also been investigated. The results were disccused by non-crystalline dynamic theory. |
