Technical physics letters Vol. 41, № 3. P. 294-297Abstract: The properties of alloys based on porous nickel-titanium (TiNi) with copper additives have been
studied. It is established that the copper doping of porous TiNi(Mo,Fe,Cu) alloys fabricated by the method
of self propagating high temperature synthesis leads to a significant decrease in the martensite shear stress
(below 30 MPa). Low values of the martensite shear stress (σmin) in copper doped TiNi-based alloys allows
medical implants of complex shapes to be manufactured for various purposes, including oral surgery. The
optimum concentration of copper additives (within 3–6 at %) has been determined that ensures high perfor
mance characteristics of TiNi based porous alloys for medical implants.
