On the process of transition of the cubic-body-centered modification into the hexagonal-close-packed modification of zirconium

The process of transition of the cubic-body-centred modification into the hexagonal-close-packed modification of zirconium can be described by means of a combination of shearing- and dilatation-processes parallel to definite crystallographic directions. The transition has, therefore, “homogeneous” or “oriented” character. See for particulars the detailed summary at the end of the paper.
