First-principles calculation i s one of the methods to calculate electronic states, providing insights into various physical properties
derived from these states. This study focuses on the utilization of first-principles calculations for Titanium （Ti） alloys. Specifically,
it explores the analysis of interstitial element diffusion mechanisms within α-Ti and material design strategies aimed at enhancing
the strength while minimizing the elastic modulus in β-Ti alloys.
