Refractory Metal Crystal Growth Techniques

  • D. W. Jones

Abstract

It is now possible to prepare many of the metal elements in single crystal form, and a continually increasing number of metal alloys are also being produced as single crystals. Concurrent with the interest in mastering problems connected with the growth of metal crystals, emphasis is also laid on realizing a greater degree of perfection both in terms of crystallinity and chemical purity. Additionally, in the preparation of single crystals of alloys, other factors have to be considered connected with constitutional studies; in some instances it is necessary to prepare not only the correct alloy in terms of composition, but at the chosen composition to retain a particular phase at a given temperature. Further, even when the requirements of crystallinity, orientation, purity, and constitutional specifications have been met, the product is not necessarily in a usable form; cutting and shaping operations are frequently required before a suitable sample is available for measurements or some specific application. This aspect is worth noting because much time and trouble can be saved by combining as many factors as possible into one operation. A redesigned measurement apparatus which can make use of the as-grown crystal, or alternatively, a modified growth-technique which embraces the parameters of orientation, purity and shape is obviously a worthwhile consideration.
