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, τ 0 , is observed below 230 K, while above this temperature τ 0 is temperature independent. At all temperatures τ 0 is found to increase linearly with c 2/3 , where c is the concentration (in atomic fractions) of cadmium as solute. The concentration dependence of τ 0 can be explained by the theory of L ABUSCH .
