Abstract
Phase equilibria in the Ti-Ni-Y system at the TiNi-YNi section are studied using physical and chemical methods (metallography, radiography, differential thermal and electron microprobe analyses). Data on hydrogen sorption and desorption by ternary system Y-Ni alloys are obtained. It is shown that the TiNi-YNi section is quasibinary eutectic with the coordinates 990 °C and ∼40 at.% Y. The solubility of Y and Ti in TiNi and YNi mononickelides is approximately + + . Based on sorption data, two hydrides may exist in the alloys with 30 to 40 at.% Y, which are thermally stable at 800 °C and over a range of 300 to 600 °C. It is revealed that the maximum amount of hydrogen at 0.1 MPa is absorbed by binary the YNi, YNi2, and YNi5 phases at room temperature.
