This paper presents the results of a defect structure investigation in commercially pure titanium alloy after hydrogen charging in a gaseous atmosphere at the temperature of 873 K up to the concentration of 5.1 at. %. Structure of samples was studied by positron lifetime, Doppler broadening and X-ray diffraction spectrometry. Several processes, corresponding to the different ranges of hydrogen concentrations were revealed. It was shown that hydrogen, penetrating in the material, expands its crystal lattice, initiates formation of vacancy-like defects of different dimensions and reacts with the last ones, forming the defect-hydrogen complexes.

AbstractThe synthesis of bis(1-tert-butyl-2 -methyl-η5 - 1 ,2 -azaborolinyl)ruthenium (1) and bis(2-methyll- trimethylsilyl-η5 - 1 ,2 -azaborolinyl)ruthenium (2) succeeds when RuCL is reacted with the corresponding 1,2-azaborolinyl lithium compounds in THF at -70 °C. Each of the sandwich complex forms two isomers with a clockwise and an anti-clockwise conformation of the azaborolinyl rings. The anti-clockwise isomer of 1 (1a ) gives colourless crystals which were investigated by singlecrystal X-ray diffraction methods. The molecular structure shows the rings in an eclipsed orientation forming an interplanar angle of 8.6 °. The isomers of 1 as well as of 2 give different 1H and 11B NMR signals.
