| 摘 要： | 本文利用静高压熔态淬火的方法,对Al_4Mn合金形成准晶的压力条件及热稳性进行了研究,在0.95GPa～4.45GPa的压力范围以10~2K/s冷却速率淬火Al_4Mn合金,在不同的压力范围得到了不同结构的准晶;并利用非晶态动力学理论就压力在准晶形成中的作用进行了初步的探讨.

| Abstract: | The condition of the formation of quasicrystal Al4Mn under high static pressure has been investigated for the first time. I-phase and T-phase have been observed in electron diffraction experiment. The structures of Al4Mn quenched at about 100C/s are different under various pressure from 0. 95 to 4. 45GPa. The phase transition from I-phase and T-phase to crystal phase-has also been investigated. The results were discussed by noncrystalline dynamic theory. |
