Abstract

We have studied the influence of silver addition in various concentrations on the structure and shape memory effect of biocompatible TiNiMoFe alloys. All these alloys at room temperature occur in a mixed state (B2 + R or B2 + R + B19′) with B2 austenite phase as the main component. It is established that small concentrations of silver (within 0.5 at % Ag) suppress the shape memory effect, while greater additions (1 at % Ag) stimulate the nucleation and growth of martensite crystals. This is accompanied by increasing content of the main B2 austenite phase and Ag particles in the alloy.
