Accurate interdiffusion coefficient, Young’s modulus and hardness are essential for precisely controlling the production of a homogeneous bio-metallic alloys with excellent properties. In this work, we utilized a combinational approach by combining the advanced diffusion multiple technique and the pragmatic numerical inverse method to efficiently determine the composition–dependent interdiffusion coefficient matrices in bcc quaternary Ti-Nb-Ta-Zr alloys at 1373 K. Moreover, the composition-dependent Young’s modulus and hardness of bcc Ti-Nb-Ta-Zr alloys were obtained by means of the nanoindentation technique.
