Strain rate sensitivity (m) and activation volume (ϑ ∗) of AISI 321 steel were studied at high strain-rate regime.m and ϑ ∗ were determined for UFG (0.24 μm), FG (3 μm) and CG (37 μm) samples.. m and ϑ ∗ remains unchanged for UFG at all investigated strain rates.. A change in both m and ϑ ∗ occurred at critical true strain rates (ε ̇ Tc) of ~5900 …
