Development of a TiNbTaMoZr-Based High Entropy Alloy with Low Young´s Modulus by Mechanical Alloying Route. Metals, 10 (11).

In this way, the optimized synthesized specimen, after 10 h of milling time, showed two di erent body-centered cubic (bcc) TiNbTaMoZr alloys, which, after sintering at 1450 C, 1 h of dwell time and a heating and cooling rate of 5 C min-1, it remained formed as two bcc TiNbTaMoZr-based HEAs. This material, with micrometric and equiaxed particles, and with homogeneously distributed phases, presented a Young’s modulus that was significantly higher (5.8 GPa) and lower (62.1 GPa) than that of the usual commercially pure (cp) Ti and Ti6Al4V alloy used for bone-replacement implants. It also presented similar values to those of the HEAs developed for the same purpose. These interesting properties would enable this TiNbTaMoZr-based HEA to be used as a potential biomaterial for bulk or porous bone implants with high hardness and low Young´s modulus, thereby preventing the appearance of stress-shielding phenomenaapplication/pdf15 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/High-entropy alloysTitaniumBiomaterialsBone tissue engineeringMechanical alloyingYoung’s modulusinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.3390/met10111463
