摘要采用Al-Ag2Al、Al-CuAl2、Al-Zn、Al-Al3Ni、Ag-Cu、liff - naf和NaF-NaCl等二元共晶混合物进行定向冷冻实验。讨论了共晶凝固的各个方面，特别提到了固体界面能的重要性。工作分为三个部分。对观察到的微观结构的描述，并讨论了在未改性共晶中发生的色散类型和杂质细胞形成对片层排列的改变。2。叙述了某些共晶定向冻结过程中择优取向的发展。3。界面分离随冻结速率的函数的测量和固体界面能对其影响的讨论。
Abstract Directional freezing experiments have been carried out with the binary eutectic mixtures, Al–Ag2Al, Al–CuAl2, Al–Zn, Al–Al3Ni, Ag–Cu, LiF–NaF and NaF–NaCl. Various aspects of eutectic solidification are discussed with particular reference to the importance of solid interfacial energy. The work is divided into three parts. I. A description of the observed microstructures, with discussion of the type of dispersion occurring in unmodified eutectics and the modification of lamellar arrangements by impurity cell formation. II. An account of the development of preferred orientations during the directional freezing of some eutectics. III. Measurements of the interphase separations as functions of the freezing rates and a discussion of the influence of solid interfacial energy upon these.
