摘要: Abstract Quasi-static and dynamic deformation behavior of a Ti48Zr20Nb12Cu5Be15 bulk-metallic-glass composite (BMGC) were investigated at cryogenic temperature (77 K). Results demonstrate that the shows good plasticity quasi-static deformation, but brittle fracture occurs during deformation. Compared with which is insensitive to strain rate, composites exhibits negative strain-rate response strength decreases increasing rate. The matrix believed dominate present BMGC Thermal softening due significant rising in shear band be responsible for temperature.
