out under different extrusion velocities and vacuum degrees. The results show that the glass transition temperature Tg of Zr55Al10Ni5Cu30 is 422.4℃, and the crystallization temperature Tx is 482.4... of maximal extrusion loads are not obvious. At 450℃, the maximal extrusion load increases with the rising vacuum degrees (2-2×10-3Pa). In superplastic forming, bulk metallic glass has larger surface friction......
