WebThe dynamic Hall-Petch relation was established by the effective grain size, which was similar at strains of up to 0.20 in Ti-15Mo alloy with static grain sizes of 29 μm and 108 μm. The decreasingly modified Hall-Petch coefficient was resulted from the successive occurrence of twinning activation, twinning suppression, and the twin ... WebJun 18, 2024 · This equation expresses that the grain size has an effect on yield point of the alloy. The Hall–Petch coefficient, k, represents the effect of grain boundaries on strength and the value is 395 MPa μm 1/2 . Therefore, the contribution of grain boundary strengthening (σ GB) can be assessed . For cold-rolled samples with 5%, 10% and 30% ... Web“dynamic Hall-Petch” effect).
