Deformation behaviours of Ti50Zr20Nb12Cu5Be13 bulk metallic glass composite in the dendrite softening region have been investigated using uniaxial compressive and tensile tests. all the compressive stress-strain curves show work-hardening phenomenon with the same tendency, the tensile stress-strain curves show work-softening phenomenon. Tests indicate that there is a migration of atomic group (about 170-180 atoms) during the deformation. The dendrite of Ti50Zr20Nb12Cu5Be13 BMGC has been well spheroidized and undergoes severe plasticity deformation after the deformation in the dendrite softening region.
