Influence of the Aging Temperature on the Mechanical Characteristics of the Nanocrystalline Ti–50.9 at.% Ni Alloy
摘要
The influence of the aging temperature in the temperature range 300–500°C on the martensitic deformation response and mechanical characteristics of the Ti–50.9 at.% Ni nanocrystalline alloy with a grain/subgrain structure has been studied. It is shown that with an increase in the aging temperature, the size and spatial distributions of Ti3Ni4 particles inside the grain-subgrain nanostructure change, which is accompanied by a shift in martensite transformation temperatures, thereby providing a change in mechanical responses from the pseudoelasticity to the shape memory effect.
