| 摘要: |
| 基于非晶形成的热力学观点,提出一种定量预测三元合金非晶形成成分范围的方法.该方法所需的三元合金的自由能是由组成三元合金的3个二元合金系统的自由能通过Toop模型外推计算得到,二元合金的形成焓则由Miedema理论计算.将该模型应用到三元合金Mg-Ni-Ce,其理论预言的非晶形成成分范围与已有的实验结果符合得较好. |

| Abstract: |
| A method for predication of the formation range of ternary amorphous alloys has been proposed from the thermodynamic point of view.Gibbs free energies of ternary alloys are calculated from the thermodynamic data of binary alloys by the Toop's method.The formation enthalpies of binary alloys are obtained by Miedema's theory.The method has been applied to predict the formation range of amorphous Mg-Ce-Ni alloys.The theoretical results are in agreement with the available experimental results. |
| Key words: ternary alloys amorphous formation range miedema's theory |
