Physical properties of the TiNi-based alloys doped with silver

A new type of biomedical shape memory alloys of the (Ti, Ni, Mo, Fe) Ag system was investigated by doping alloys with different concentration of Ag to 1.5 at. %. The role of an electronic factor of basic and alloying elements in the studied alloy was established. Martensitic transformations in TiNi-based alloys were studied for a series of initial and thermo-mechanically treated samples, i.e. after rolling, and the diagrams of the martensitic transformation of the (Ti, Ni, Mo, Fe) Ag system were constructed. It was revealed that rolling shifts the characteristic temperatures of martensitic transformations towards lower temperatures in comparison with the initial alloys which were not subjected to thermo-mechanical treatment.
