Fracture surface profile of tensile specimens from the outer to the inner surface (top and bottom of the images) (a) T-A and (b) T-Z. (c) shows the aligned inclusions surrounded by cleavage in areas of predominantly rupture fracture observed in sample T-E. (d) EDS analysis of the inclusions at 25 kV and a 15 mm of working distance. FE-SEM images were obtained with 15 kV, a working distance of 31 mm approximately and in resolution mode.
