(a, b) dislocations accumulated around the precipitates and α-martensite laths under the double beam condition, respectively. The SAED pattern in Fig.5b confirms the existence of α-martensite laths (c1, d1) dense deformation twins formed between α-martensite laths and in the interior of annealing twins, respectively (c2, d2) the corresponding SAED patterns to Figs.5c1 and d1, respectively
