Room-temperature creep resistance of Co-based metallic glasses
The room-temperature creep resistance of the Co56Ta9B35 metallic glass was determined by a nanoindentation technique. Results showed that the creep curves were described by a generalized Kelvin model. The low creep strain-rate sensitivity parameter and creep rate derived from the displacement–holdin...

| description | The room-temperature creep resistance of the Co56Ta9B35 metallic glass was determined by a nanoindentation technique. Results showed that the creep curves were described by a generalized Kelvin model. The low creep strain-rate sensitivity parameter and creep rate derived from the displacement–holding time curves demonstrated the high creep resistance of the Co56Ta9B35 metallic glass. The deformation mechanism causing the nanoindentation creep was discussed based on the “shear transformation zone” concept, which gave an explanation for the creep behavior in metallic glasses. |
