It may be observed that the microstructure of 3% deformed specimen (after annealing at 900 °C for 2 and 15 mins) shows the presence of planar slip bands inside FCC grains (Fig. and)) ). The black arrows in Fig. and) show that deformation of B2 precipitates (in as-annealed condition) mostly occurs near FCC/B2 interfaces with a low dislocation density inside B2 . On increasing the strain to 10%, there is a decrease in spacing between planar slip bands within FCC grains (Fig. and)) with an increase in dislocation density inside B2 precipitates (Fig. and)) ).
