The thermo-mechanical treatment was chosen to correspond to the production of wire with suitable mechanical properties for dental implants. After casting the alloy was hot forged (700–900 degC), solution treated (850 degC/30 min, water quenched) and cold swaged (reductions up to 91%). The annealing (700 degC/3 h/furnace) or aging (450 degC/8 h/furnace) was used as final heat treatment. The microstructure was studied by using light microscopy, scanning electron microscopy, transmission electron microscopy and XRD analysis. Cold swaging introduces microstructure consisting of highly deformed Beta-phase grains with dislocation tangles and twins, which ensures high tensile strength about 820 MPa, low Young's modulus (~ 50 GPa) and good ductility ~ 10%. Subsequent aging increases tensile strength (1000 MPa) as well as Young's modulus (75 GPa) without diminishing ductility. Annealing at 700 degC slightly decreases tensile strength (730 MPa) and increases the ductility and Young's modulus (17% and 62 GPa respectively). The mechanical properties attained recommend the thermo-mechanical treatment for production of wires for dental implants. ER -
