Abstract: Pt_<60>Ni_<15>P_<25> metallic glass ribbons prepared by a single-roll melt-spinning method were deformed in tension at a strain rate of 2 × lO^<-2>s^<-1> in the supercooled liquid region. In-situ observations of the deformation behavior of the metallic glass ribbons were carried out by using an optical microscope. It was found that a homogeneous deformation of more than 200% elongation was taken place by a viscous flow of supercooled liquid of the Pt_<60>Ni_<15>P_<25> metallic glass at 523K, a medium temperature among the supercooled liquid region. In the case of tensile tests after partially crystallized at 543K, it was found that the residual supercooled liquid deformed preferentially without deformation of the crystalline solid, and therefore an inhomogeneous deformation occurred.
