Abstract
In this study, binary interdiffusivities of bcc titanium-scandium (Ti-Sc) alloys in the temperature range of 1273 K to 1473 K were determined by combining the diffusion couple technique and Boltzmann–Matano method. In addition, the composition-dependent Young’s modulus and hardness of bcc Ti-Sc alloys were obtained using the nanoindentation technique. The results reveal that a small amount of Sc additive can be very beneficial to bio-Ti alloys with good properties.
