Grain-size-independent plastic flow at ultrahigh pressures and strain rates

HS Park, RE Rudd, RM Cavallo, NR Barton, A Arsenlis… - Physical review …, 2015 - APS
A basic tenet of material science is that the flow stress of a metal increases as its grain size
decreases, an effect described by the Hall-Petch relation. This relation is used extensively in …
