چکیده انگلیسی
The deformation of a Ti-based metallic glassy composite in the supercooled liquid region was studied by compression tests at variable strain rates. The composite consists of a glassy matrix and a dendrite phase reinforcement. The stress-strain curves are characterized by a stress-overshoot, work-hardening and superplasticity. The superplasticity is the co-effects of lattice distortion and the multiplication of dislocations in dendrite phase, the homogenous viscous flow of the glassy matrix, and the formation of ordered and disordered domains at the glass/dendrite interfaces. A constitutive relationship is built based on the strain compensation Arrhenius model to provide an insight into hot forming processes.
