Unified Hall-Petch description of nano-grain nickel hardness, flow stress and strain rate sensitivity measurements
It is shown that: (i) nano-grain nickel flow stress and hardness data at ambient temperature follow a Hall-Petch (H-P) relation over a wide range of grain size; and (ii) accompanying flow stress and strain rate sensitivity measurements follow an analogous H-P relationship for the reciprocal “activat...
