The crystallography and deformation modes of hexagonal close-packed metals

摘要: The extensive data on the metallography and crystallography of face-centred cubic and body-centred cubic metals have been the subject of several reviews in recent years, but in comparison the data for hexagonal close-packed metals remain dispersed in the literature. This is unfortunate, since the hcp structure presents a number of confusing features not encountered in cubic structures. With the increasing technological application of hcp metals, there does appear to be a need for a summary of the structure of these metals, with …
