Spectrum and energy measurements of X-ray radiation emitted by partially transparent Fe and Al plasmas have been carried out for thin-layered inverted-corona targets on the ISKRA-5 laser facility. The targets were plastic spherical (2-mm diam) shells of 4.6 mm thickness having 0.25 mm Fe or 0.65 mm Al thin inner coatings. The energy radiated in Heα and Lyα resonance lines of Fe and Al ions was measured as well. Experimental data and results of numerical calculations are compared. Measured laser light to X-ray conversion coefficient has been found to be essentially low, then calculated one for both Fe and Al coated targets. Possible reasons for this discrepancy are discussed.

The structure and mechanical properties of Y-TZP nanoceramics produced by ultrasonic (US) action on nanostructured ZrO2 – 5.4wt% Y2O3 powder have been analyzed. The influence of powder US-treatment on elastic aftereffect of a compact, uniformity of ceramics volumetric shrinkage, on ceramic nanostructure forming and as a result on its density, hardness, impact strength was shown. The optimum of power level of US-action was defined.
