(a) Fracture surface (X-Z plane) of a tensile specimen Set A after rupture. Yellow-dashed arrows show LoFs. (b) Region b in (a) with a higher magnification showing the start of failure from a lack of fusion (LoF), (c) region c in (a) with a higher magnification indicating another LoF, (d) region d in (c) with a higher magnification showing dimple-like features, (e) region e in (b) with a higher magnification indicating vein-like patterns, (f) a porosity arrests a crack and multiple shear bands are found, (g) fracture surface (X-Z plane) of a tensile specimen C, and (h) region h shown in (g) with a higher magnification.
