THE NUCLEATION AND DEVELOPMENT OF A RECRYSTALLISED STRUCTURE.

Abstract

In an attempt to determine the mechanism of recrystallisation in zinc, the modes of deformation, which occur at high temperatures when a bicrystal of zinc is sheared along its grain boundary, are being investigated. Towards this end, apparatus for growing bicrystals has been designed and built. Single crystals of zinc, for use as seed crystals, have been grown. Work is progressing towards a method of casting very pure zinc in a bicrystal mould and for seeding the polycrystalline casting for the growth of bicrystals of closely controlled orientation. Techniques for optical, electron microscopical and X-ray diffraction examination of the structure of the bicrystal are currently being developed. (Author)
