The compression textures of polycrystalline materials of caesium chloride structure type

Abstract

Specimens prepared by compressing, in a steel die, powders of CsC1, T1C1 and NH4C1, at up to 75 tons/in. ~, are investigated by electron diffraction. The compression textures under these conditions are fotmd to be (111}. This texture is shown to be expected on the basis of slip on the usual systems, i.e. {011}, (100).

Systematic hardness measurements on single crystals and polycrystalline blanks of cesium halides

“…Studies of polycrystalline aggregates of NaCl and KCl are reported by Dobson and Wilman (1962a), Subramanyam (1962), Armington et al (1973) and Leuenberger et al (1981). With the exception of an electron diffraction study of CsCl (Dobson and Wilman 1962b), there is no report of any study on the polycrystalline aggregates of the cesium halides.…”

The re-orientation caused by unidirectional abrasion on materials of CsCl structure type

“…The surface re-orientation caused by abrasion on materials of NaC1 structure type has been investigated recently by Dobson &Wilman, 1961 andKing &Wilman, 1961. In the experiments described below, the structure of the surface and sub-surface regions of four typical salts (CsC1, T1C1, NH4C1 and NH4Br) of CsC1 structure type, abraded on 4/0 emery paper (of particle diameter 5 microns), have been investigated by electron diffraction.…”
