| Abstract Scope |
Heterogeneously structured materials play a crucial role in recent advancements because of their unique ability to balance strength and ductility. We used the harmonic-structured design concept on the Ti-24Nb-4Zr-8Sn alloy, which is a β-metastable titanium alloy. After processing, we carried out microstructural and mechanical characterizations. The harmonic design notably increased the yield strength of the Ti-24Nb-4Zr-8Sn alloy without compromising its ductility. However, we observed that the shell fraction should not exceed a certain threshold, beyond which both strength and ductility are compromised. The control over respective grain sizes in the core and shell during the powder metallurgy process, and the need for significant differences in grain size between both regions for improved mechanical behavior of the harmonic material, highlight the practical implications of our research, making our findings directly applicable to the field of materials science and metallurgy. |
