| Abstract Scope |
Titanium alloys with excellent properties are attracting attention as key materials for high value-added parts. In particular, Ti-based powders are being actively studied for application in metal additive manufacturing processes for industrial. While crystalline Ti alloys (commercially pure titanium and Ti-6Al-4V) are commonly used in metal additive manufacturing, recent research efforts have been expanding toward the use of Ti-based metallic glass alloys with superior corrosion resistance and mechanical properties.
In this study, a Ti-based amorphous alloy was designed to exhibit enhanced corrosion resistance even under harsh environments. For this purpose, powders and ribbons of Ti-based amorphous alloys containing various contents of misch metal were prepared. The designed alloys exhibited improved corrosion resistance in 10 vol.% H₂SO₄ solution compared to both conventional crystalline Ti alloys and existing amorphous alloys. These findings demonstrate the potential of the designed Ti-based amorphous alloy as a promising material for advanced applications requiring durability and manufacturability. |
