如果两个晶格之间存在严格的取向关系，那么从β晶粒的体心-立方-六边形-密堆积相变中继承的几个α片的取向的知识使我们能够确定后者的取向。这篇文章讨论了解的唯一性问题，并得出结论，在不太有利的情况下，所需的不同α取向的数量是3个，但在最有利的情况下减少到2个。
Knowledge of the orientations of several α plates inherited from the body-centred-cubic–hexagonal-close-packed phase transformation of a β grain allows us to determine the orientation of the latter, provided that a strict orientation relation between the two lattices exists. This contribution discusses the problem of the uniqueness of the solution and leads to the conclusion that the number of different α orientations required for that purpose is three in the less favourable case but is reduced to two in the most favourable case.
