After the annealed sample is immersed in liquid nitrogen, the low-temperature shrinkage causes the initial dislocations to decompose and form a large number of stacking faults, as shown in Figure 4(b).
After the annealed sample is immersed in liquid nitrogen, the initial dislocation will decompose due to low temperature shrinkage, and a large number of stacking faults will be formed, as shown in Fig. 4 (b).<br>
After the annealing specimen is immersed in liquid nitrogen, low temperature contraction causes the initial dislocation to break down and creates a large number of layer errors, as shown in Figure 4 (b).
