Comparison of dislocation mobility in LiF measured by direct and indirect methods

physica status solidi (a) (1976)

A. A. Urusovskaya G. G. Knab Y. Estrin

A comparison is made of the effective stress dependence of the dislocation velocity V in LiF crystals as determined by stress relaxation tests and by direct etch pit measurements. The stress relaxation technique used permits to study both the effective stress dependence of V and the evolution of the total and mobile dislocation densities during the dynamic loading of the crystals. The data obtained by the two methods are in good agreement. It is shown that the density of mobile dislocations is decreasing with the strain, whereas the total dislocation density is growing during the dynamic straining to 1%. [Russian Text Ignored]

Influence of Irradiation with Heavy Ions on the Defect Structure and Mechanical Properties of LiF Crystals

physica status solidi (a) (1982)

Liya L. Regel V. R. Regel S. E. Boriskin G. G. Knab A. A. Urusovskaya

By means of several methods (fractography, selective etching, electronography, absorption spectroscopy, optical microscopy in transmitted polarized light, measuring of the temperature dependence of conductivity, estimation of mechanical properties by microhardness, yield point and dimension of dislocation rosettes) the nature of damages created in LiF crystals by bombardment with heavy ions (carbon, chromium, and xenon) having high energy (up to 100 MeV) is studied. It follows from the results that the effect of implanted heavy ions on the defect structure is complicated. A sputtering or/and evaporation of LiF from the irradiated zone is discovered; there are strong damages including radiolysis effects inside this zone. Changes beyond the implantation zone are revealed, where the traces of the spreading shock wave and secondary ionizing radiation are evident. [Russian Text Ignored].

Abstract Experimentally (by filming and selective etching methods) and theoretically (by means of the analysis of stress distribution near breaks on the surface at places where kink‐band boundaries are nucleated) mechanism of kink‐band generation and developing is investigated.

Peculiarities of the interaction of accelerated₁₂C⁺⁶ions with LiF crystals

Radiation Effects (1984)

V. R. Regel Л. И. Алексеева A. A. Urusovskaya G. G. Knab G. V. Sotserdotova

Abstract Comparing the experimental data with the known theoretical knowledge about interaction of irradiation with a substance one can conclude that the appearance of colour centres in the bulk of a LiF crystal is the result of a channelling motion of accelerated C+6 ions, accompanied by the creation of neutrons due to the decay of lithium ions.
