The effect of thermal treatment upon the yield strength and some optical absorption parameters were investigated for NaCl crystals containing different amount of divalent nickel. It has been shown that the main changes of the structure-sensitive characteristics occur in two temperature ranges. In the low-temperature range (room temperature-473 K) the yield strength of crystals does change drastically whereas the optical parameters of annealed samples become similar to those characteristic of

On the . other hand, the high-temperature annealings (473-673 K) mainly affect the optical characteristics remaining the mechanical ones -more or 1ess simil a r t o t h o s e t y p i c a l o f t h e s o l u t i o n t r e a t e d s t a t e .
