This analysis shows that combined processing enhances mechanical properties in Ti-13Nb-13Zr alloy, suggesting its viability for biomedical applications.
Ultrafine-grained materials are currently of great interest due to their excellent mechanical and functional properties. One of the most effective methods to obtain such materials with a unique combination of microstructure and properties is intense plastic deformation (IPD). This paper deals with the development of an efficient IPD method for Ti-13Nb-13Zr titanium alloy based on a combined approach involving equal channel angular pressing (ECAP) and subsequent rotational forging compression (“RFC”). Ti-13Nb-13Zr titanium alloy was pressed at different temperatures using an equal channel angular pressing (ECAP) process through a channel angle of 130° for several passes, followed by rotational forging compression (“RFC”). Microstructural analysis showed that the application of combined processing (RCUP + RFC) transformed the coarsegrained (CG) structure into an ultrafine-grained structure (UFGS). In addition, the results of mechanical tests indicate that the application of combined processing method significantly increases the hardness and modulus of elasticity of titanium alloy Ti-13Nb-13Zr. These changes in the complex of properties allow us to consider this alloy as a highly effective alternative to traditional metallic materials used inbiomedical implantology.
