The carried investigation revealed the possibility to produce nanostructured
Ti from cpTi grade 4, by equal-channel angular pressing
(ECAP) followed by thermo-mechanical treatment (TMT). The nTi produced
presented higher ultimate strength and yield strength than conventional
cpTi grade 4, without an important ductility reduction. These
increased strength properties, added to the higher biocompatibility and
higher corrosion resistance in body fluids of cpTi, when compared to
Ti-6Al-4 V alloy, made nanostructured Ti useful to implants in medical
applications [26].
