Using the decoration technique, the dislocation structure has been observed in regions localized near precipitates in nickel‐doped NaCl crystals. The results are interpreted in terms of the stress‐operated mechanism for the generation of prismatic dislocations by the precipitates. Normally only two of twelve possible slip directions operate for 〈110〉 rods. This is accounted for in terms of the climb and disappearance of dislocation loops corresponding to the other directions. {100} plates produce loops spreading along for 〈110〉 directions.
