the analysis of the variation in area percent of {100}, {101}, {111} and {112} planes with the directions L and C was made, results are shown in Fig. 5. It is seen that the area percent of the {100} and {112} planes is fairly uniform, and thus the distribution of these planes is unlikely to affect the anisotropy of the mechanical properties. However, the proportion of the {110} and {111} planes changes significantly from the L to the C direction. Because of the most densely packed planes in BCC are {101}, implies that the increase in grains oriented in this specifics crystallographic planes might lead to increase the amount of plastic deformation and thus the fracture toughness in the C direction.

In order to assert the previous comments, the discrete pole figures are shown in Fig 6 which were obtained from the inverse pole figures. These pole figures sustain the absence of a preferential orientation in the sample, it could be seen a homogenous density in all families plane orientations.
