Seventy years of Hall-Petch, ninety years of superplasticity and a generalized approach to the effect of grain size on flow stress
The grain size, and therefore the grain boundary density, is known to play a major role in the
flow stress of metallic materials. A linear relationship to the inverse of the square root of the …
