摘要：

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 173-373 K. The results demonstrate that hydrogen diffusion in the material bulk provides gradual suppression of B2 -> B19' and R -> B19' transformations and that the temperature of B2 -> R 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. (C) 2018 Elsevier B.V. All rights reserved.
