The tensile deformation behavior and the workability of Zr_Al_Ni_Cu_ Metallic Glass with a wide supercooled liquid have been examined. The glassy solid exhibited the homogeneous deformation at higher temperatures and lower strain rates. The supercooled liquid revealed a homogeneous deformation even at high strain rates above 0.5 s^. The strength in the homogeneous deformation region was lower at higher temperatures and lower strain rates. The supercooled liquid exhibited similar deformation behavior to the other high-strain-rate superplastic materials. Using this superplastic-like deformation in the supercooled liquid, complex-shaped glassy component with original strength was produced through an extrusion process
