The strength of single crystals of inorganic salts under high pressure, III

Abstract

Based on the results of the plastic deformation of five alkali halide single crystals shown in Part II of this series the values of the distance L over which a dislocation can be propagated in the crystal given in Taylor's equation were calculated. The obtained values of L are about 2×10^-4cm for lithium fluoride and sodium chloride, 5×10^-4cm for potassium chloride and potassium bromide, and 16×10^-4cm for potassium iodide. Also, the pressure effects on the various factors in Taylor's equation were investigated, and the values of L under high pressure were calculated. 1.4×10^-4cm for lithium fluoride and sodium chloride, and 2.8×10^-4cm for potassium chloride were obtained under hydrostatic pressures up to 1000kg/cm^2.
