Internal stresses and phase transitions in gradient Ti-Nb materials prepared by wire additive manufacturing
Annotation in Czech
Additive manufacturing (AM) enables the production of components with controlled chemical gradients, yet challenges like porosity and low fracture toughness persist. Among AM techniques, two-wire arc additive manufacturing stands out for its high deposition rate, cost-effectiveness, and precise compositional control. This method is particularly promising for biomedical applications, such as hip joint implants, where varying mechanical properties are advantageous. By employing the Ti-Nb alloy system, this project aims to optimize implant design by tailoring elasticity and strength along the femoral stem. Metastable β-Ti alloys facilitate this approach, as slight compositional changes significantly influence mechanical properties. The study investigates the potential of graded Ti alloys produced through wire AM to enhance biomedical performance, with a particular focus on internal stresses and phase transformation in graded Ti-Nb alloys.
