评述了过去20多年来有关合金调幅分解和连续有序化过程的研究情况,指出这种普遍化处理实质上澄清了合金中有序/无序反应。浓度波理论和倒易空间的近似方法提供了研究连续相变的基础,运用这些概念结合自由能-成分和相图系统评述了连续相变中的基本规律。最后根据我们的最近研究结果讨论了有序化和调幅分解共存反应的实质,并提出了利用连续相变使合金产生天然纳米材料的新概念以及合金中产生天然纳米组织的成分设计和制订热处理工艺的基本准则。
Review of the research on amplitude modulation decomposition and continuous ordering process of alloy over the past two decades indicates that this generalization process substantially clarifies the orderly / disorder reaction in the alloy. The approximation method of concentration wave theory and reciprocal space provides the basis for the study of continuous phase transformation. The concept of continuous phase transformation is commented by combining these concepts with the free energy - component and phase diagram system. Finally, according to the results of our recent research, we discuss the essence of the coexistence reaction of ordering and amplitude modulation decomposition. We also propose the new concept of using continuous phase transformation to produce natural nanomaterials in alloy and the composition of natural nanostructures in alloy and design heat treatment process The basic guidelines.
