Size effects in cobalt plastically strained in tension: impact on gliding and twinning work hardening mechanisms
Mechanical properties in tension of cobalt have been studied in a wide range of grain size d using thickness t of samples from 125 to 700 μm. The Hall and Petch (HP) relationship indicates that the yield stress strongly varies for t/d below a critical value around 14, highlighting the existence of a...
