Aleaciones de titanio beta de media-alta entropía procesadas por deformación plástica severa: caracterización microestructural, mecánica y biológica para aplicaciones odontológicas

The development of biomaterials for medical and dental applications faces the challenge of combining biocompatibility, corrosion resistance, and suitable mechanical properties. Conventional alloys such as Ti-6Al-4V and NiTi present limitations related to toxic ion release and discrepancies between their elastic modulus and that of human bone. In this context, β-phase titanium alloys stabilized with biocompatible elements such as Nb, Ta, Mo, and Zr represent a promising alternative. This project aims to develop and characterize medium- to high-entropy β-Ti alloys processed by severe plastic deformation techniques, specifically high-pressure torsion (HPT), in order to evaluate their microstructural, mechanical, electrochemical, and biological properties for dental applications. The research is structured into three phases: (1) alloy fabrication using HPT, (2) analysis of processing effects on alloy properties, and 3) evaluation of electrochemical behaviour of dental prototype under in vitro conditions. The expected outcomes include alloys with enhanced biocompatibility and mechanical performance, as well as the preliminary validation of a prototype with potential clinical applications. This project will contribute to innovation in metallic biomaterials, the training of specialized human resources, and the strengthening of research capacities at the Instituto Tecnológico de Costa Rica. It is aligned with national policies, the Sustainable Development Goals (SDGs 3, 4, 5, 8, 9, 10 y 12), and the TEC Strategic Knowledge Axes 2023–2032, particularly Health and Industry.
