摘要	We report seven TiZr-based bulk metallic glasses (BMGs) developed in the Ti-Zr-Cu-Fe-Be alloy system with critical sizes over 20 mm for glass formation. Especially, the melts with compositions of Ti31.9Zr33.4Cu8.7Fe4Be22 (at.%, No. 6 alloy) and Ti32.8Zr30.2Cu9Fe5.3Be22.7 (No. 7 alloy) can directly solidify into 150 g glassy ingots, and the No. 7 alloy could be cast into an amorphous rod with a diameter of 50 mm and a height of 75 mm by the simple copper mold casting method. Yield strength, maximum strength, the increase of true stress after yielding, and compressive plastic strain of No. 6 BMG are 1720 MPa, 2010 MPa, 165 MPa and 8%, respectively. Other BMGs show similar mechanical properties with compressive plastic strains more than 5%, concomitant work hardening-like behavior. A parameter named as angles of spherical compositional vectors (ASCVs) was proposed to quantitatively evaluate the discrepancy between two multiple-component compositions. These plastic BMGs with exceptional GFA in the Ti-Zr-Cu-Fe-Be alloy system have enriched the family of BMGs and may have scientific significance on developing advanced BMGs for practical applications.
