Abstract
The short-term creep processes in a Ti–55.7 wt % Ni alloy are investigated. Wire samples of this alloy after preliminary annealing at 450–700°C are deformed by torsion under constant loading in an air atmosphere in the temperatures range 450–550°C. The effect of structural parameters (grain size, presence of fine Ti3Ni4 particles) on the creep mechanism and rate is shown. Grain-boundary diffusion is found to be one of the main creep mechanisms.
