Mechanical properties of ZrCuTi thin film metallic glass with high content of immiscible tantalum
چکیده انگلیسی

The ZrCuTi thin film metallic glasses (TFMGs) with immiscible Ta were successfully fabricated via co-sputtering. The glass forming composition for ZrCuTi–Ta TFMGs ranges from 0 to ~ 75 at.% of immiscible Ta, distinctly different from bulk metallic glasses (BMGs). When Ta content is over 75 at.%, the amorphous TFMG structure gradually transforms to nanocrystalline β-Ta. The mechanical properties are strongly influenced by Ta content. The elastic modulus remains nearly constant over 0–50 at.% Ta, and increase rapidly over 50–100% Ta. The key factor appears to be the population of the Ta–Ta strong bonds. The highest elastic modulus and hardness up to ~ 140 GPa and 10 GPa, respectively, of the Ta-rich TFMGs, much higher than the Zr-, Cu- and Ti-based amorphous alloys, might be useful for applications.
