In this paper investigations of electrical and mechanical properties of ternary mercury chalcogenides Hg1−xCdxSe, HgSe1−xSx, HgTe1−xSx were performed subjected to hydrostatic pressure treatment. The influence of cation and anion substitutions was tested on the electrical resistivity dependence of P and microhardness H values before and after applying pressure P up to 2.3 GPa. The variations of both the start pressure Pt of sphalerite B3 to cinnabar B9 structure transformation and also H as a function of chemical composition were obtained. A macroscopic bending of the samples found after reversible phase transformations suggests the increase of plasticity in the vicinity of phase transition point. The measurements performed have confirmed the sharp variation in both the electrical and volumetric properties of samples at the beginning of B3→B9 phase transition in contrary to slow structural transformations obtained by x-ray and synchrotron investigations.

Features of penetration into copper barrier and in the barrier made of iron alloys are viewed. At creation of "channel" elements initiation is viewed. Regulation of superdeep penetration due to preliminary refrigeration strikers and barrier up to-1960С is shown. Expenses of energy for superdeep penetration are reduced ≈ 180 times.
