Abstract

New shape memory alloy (Ti-20Nb-10Ta-5Zr) for production of minimally invasive implantation medical devices (cava filter) was tested for static mechanical properties. The material for investigations was wires with different thickness before and after thermal treatment in various conditions and surface mechanical treatment. The structure was investigated on a scanning electron microscope and on a Auger spectrometer. High indicators of strength and ductility were noted. The mechanical treatment of the surface and annealing in vacuum best affect it.
