Abstract

The deformation behavior of bulk nanocrystalline Fe₈₈Si ₁₂ alloy has been investigated with compression tests at different strain rates. The activity volume v is 6b³ which indicates that the deformation mechanism is controlled by the dislocation slip. On the other hand, the critical size of the nanocrystalline Fe₈₈Si₁₂ alloy for deformation mechanism is calculated to be about 5.3 nm. It is smaller than the grain size of the nanocrystalline Fe₈₈Si₁₂ alloy (10 nm), which also indicates that deformation mechanism of the nanocrystalline Fe₈₈Si₁₂ alloy is controlled by the dislocation pile-up.
