dc.description.abstract | Metallic glasses (MGs) have garnered significant attention for the possibility to use as advanced structural materials in recent decades. However, their high processing costs remain a major obstacle to their commercialization. This research offers a practical guideline to significantly reduce production costs through tailored alloy design and precise control of thermoplastic forming (TPF) process parameters. Specifically, we discovered commercially available MGs with a low glass transition temperature (Tg) can be developed in the Zr-rich alloy systems. Moreover, we addressed the challenge of maintaining a wide TPF window in Be-free Zr-based MGs while keeping Tg low. Our research has yielded the development of Be-free Zr-rich multicomponent MGs with a low Tg below 350 °C (623 K) and a wide TPF window of over 70 K, resulting in excellent thermoplastic formability (TPFA). Notably, the MGs we developed exhibit a lower Tg than advanced engineering plastics like Polyimide and Polybenzimidazole, which suggests that the TPF process of plastics could be extended to MGs. In addition, we employed Flash-DSC to accurately identify the TPF window and TPFA according to the heating rate in a wide range from 10-1 to 104 K/s, and proposed novel TPFA parameters that are based on continuous heating transformation diagram with iso-viscosity contours. Our findings demonstrate that even marginal MGs have a significant advantage in manufacturing micro-to-nano scale products that can be molded at ultra-fast heating rates, similar to advanced engineering plastics. Indeed, this work will undoubtedly inspire us to further explore the potential of MGs as a practical material for industrial applications. © 2023 The Authors | - |
