Ti-based bulk metallic glasses (BMGs) are very attractive for engineering applications because of their outstanding properties such as high specific strength, good corrosion resistance, etc. However, the relatively poor thermoplastic formability greatly restrain their wide application. In this study, a series of novel lightweight Ti-based BMGs with enhanced thermoplastic formability have been developed by alloying method based on a Ti41Zr25Be34 alloy. The improvement mechanisms of thermoplastic formability induced by different alloying elements have also been systematically studied. The representative Ti41Zr25Be28Fe6 alloy possesses a wide supercooled liquid region of ~123 K and low viscosity of ~106 Pa s in its supercooled liquid region, resulting in a superior thermoplastic formability. Moreover, the good GFA and excellent mechanical properties of Ti41Zr25Be28Fe6 alloy also make it applicable as engineering materials. This work will greatly promote the development and application of Ti-based BMGs.
