Atomic-Scale Comparison Between Twin Growth Mechanisms in Magnesium
The two most frequently observed twins in hexagonal close-packed (HCP) Mg
and twins
have surprisingly different properties and morphologies
with twins appearing under higher stresses and being much thinner than twins. By considering the atomic-scale elementary properties of the twin interfaces and their disconnections
we show that (1) the transverse propagation of twins is hindered by the absence of low-energy mobile interfaces
whereas twins benefit from prismatic-basal interfaces and (2) the thickening of twins is slowed by higher energy barriers against both the nucleation and propagation of disconnections along their interfaces.
