| Abstract: | The investigation of the dependence of indentor intrusion depth on the time of load application and temperature for the alkali-halide crystals KCl, LiF, NaCl has been carried out. The dependence of indentor intrusion velocity logarithm lg ḣ in microhardness H appears to be linear in the investigated interval of loading times and temperatures. The data obtained may prove the thermofluctuational character of the microindentation process. — The activation energy of microindentation process almost coincides with the activation energies of the sublimation process. |
