A ternary Co₆₁Nb₈B₃₁ bulk metallic glass with plasticity of 5% and yield strength of 5200 MPa was fabricated. It is shown that the primary crystallization product of the Co₆₁Nb₈B₃₁ glass is the vertex- and edge-sharing Co₆₁Nb type phase. The enhanced plastic strain is consistent with the observed multiple shear bands that can redistribute the internal shear stress. The appreciable plastic strain favors the formation of metallic bonding network-like structure and holds high Poisson's ratio.
