Abstract

Dislocation structures arising in indentation on the (111) face of NaCl single crystals are studied by etch‐pit technique. The deformation temperature varied in the interval from 77 to 520 Β°K. The effect of radiation defects introduced by γ‐irradiation on the shape of dislocation rosette was investigated. Three types of dislocation rosettes depending on the experimental conditions were observed. A possible explanation of this phenomenon is proposed. It is shown that the polarity of plastic deformation observed under indentation is an universal phenomenon which is revealed in the temperature range from 77 to 470 Β°K. The phenomenon of dislocation rosette inversion was first observed.
