Solution hardening of zinc crystals with aluminium and copper additions during the tensile test

Abstract

Zinc single crystals, containing varying amounts of copper or aluminium, have been subjected to plastic deformation in the uni-axial tensile test in the temperature range of 173–473 K. The effect of the alloying additions and temperature on: initial forest dislocations density ρ f (0001), critical resolved shear stress (CRSS) value in the basal and pyramidal systems, twinning stress τ T value in the {10–12} 〈1̄011〉 systems has been tested. Photographs of the etch pits before and after plastic deformation of the single crystals tested have been presented.
