| Abstract: | Solid solution hardening in single crystals of magnesium containing cadmium (up to 2.4 at.%) has been investigated in the temperature range 77 K to 295 K. A strong temperature dependence of the critical resolved shear stress, τ0, is observed below 230 K, while above this temperature τ0 is temperature independent. At all temperatures τ0 is found to increase linearly with c2/3, where c is the concentration (in atomic fractions) of cadmium as solute. The concentration dependence of τ0 can be explained by the theory of LABUSCH . |
