Vickers Hardness Anisotropy and Slip System in Zinc (Tris) Thiourea Sulphate Crystals

Abstract

The Vickers hardness indentations on the two major habit planes (100) and (001) of the solution grown ZTS crystal have been carried out at various azimuthal orientations of the indentor, keeping other variables constant. The observed anisotropic variations have been explained on the basis of effective resolved shear stress on the active slip system in the crystal. The detailed results are reported in the paper.
