Summary: | The effects of Ta and Hf on the dynamic Young's moduli and tensile properties of Ti–Ta and Ti–Hf alloys for biomedical applications are comparatively studied in this paper. It is found that with increasing Hf content, the dynamic Young's modulus of the Ti–Hf alloy gently decreases and its tensile strength keeps on increasing. In contrast, with increasing Ta content, the dynamic Young's modulus of the Ti–Ta alloys first decreases, reaches a minimum value of 69
GPa and then increases. In parallel, the tensile strength first increases, reaches a maximum value of 587
MPa, and then slightly decreases. It is shown that the addition of Hf has a slight influence on the dynamic Young's modulus and a strong influence on the tensile properties of the Ti–Hf alloy, while an increase of Ta content has a strong effect on both the dynamic Young's modulus and tensile properties of the Ti–Ta alloy. |
