Abstract
The effect of surface processes due to heat treatment on the flow stress of NaCl crystals doped with different divalent impurities is investigated. The results show that in the surface layer of the crystals annealed in air some chemical reactions take place leading to substantial changes in surface conditions and thus in the flow stress of the crystals. The effect may dwarf the flow stress increment caused by dipole—dislocation interaction in the bulk, and may be the reason for some contradictory results in the literature.
