Abstract
The report presents research data showing how the phase state and transition temperatures in hydrogenated nanocrystalline and coarse-grained TiNi alloys are influenced by hydrogen redistribution on their aging at room temperature. The research methods include four-point measurements of resistivity as a function of temperature and differential scanning calorimetry at 173-373â¯K. The results demonstrate that hydrogen diffusion in the material bulk provides gradual suppression of B2âB19â² and RâB19â² transformations and that the temperature of B2âR transformation is hardy sensitive to hydrogen. Also presented is an analysis of the mechanism by which hydrogen acts on the temperatures and sequence of martensite transformations.
