The use of the primitive cell volume and the zero order Laue zone (ZOLZ) pattern is proposed as a means to identify phases in a complex microstructure. A single convergent beam pattern, containing a higher order Laue zone ring, from a nanosized region is sufficient to calculate the primitive cell volume of the phase, while ZOLZ pattern is used to determine the zone axis of the crystal. A computer program is used to screen out possible phases on the basis of the value of measured cell volume. The indexing of the ZOLZ pattern follows in the program to find the zone axis of the identified phase. Combination of these two methods ensures accuracy and reliability of phase identification from a single CBED pattern. An example of the analysis is given from the rapidly solidified Al-Al3Ti system.
有人提出使用原胞体积和零阶劳厄区（ZOLZ）图案来识别复杂微观结构中的相。来自纳米区域的包含高阶劳厄区环的单个会聚束图案足以计算该相的原胞体积，而ZOLZ图案则用于确定晶体的晶带轴。使用计算机程序根据测量的晶胞体积值筛选出可能的相。程序中对ZOLZ图案进行指标化以找到所识别相的晶带轴。这两种方法的结合确保了从单个会聚束电子衍射（CBED）图案进行相识别的准确性和可靠性。给出了快速凝固的Al-Al3Ti体系的分析示例。
