Mechanism of grain boundary serration during hot deformation .
WEBFeb 1, 2020 · Fig. 4 a shows a different behavior of the GB serration than that induced by only GBDs. In Fig. 4 a, the GB serration was caused by the incoming disloion array (Fig. 4 b) with a constant disloion spacing over a long range. The constant disloion spacing implies that incoming disloions did not pile up and dissociated into GBDs rapidly.
