It's been reported the occurrence of hydrogen induced inter-granular or transgranular quasi-cleavage fracture largely depends on tramp element (P, Sb, Sn, As) segregation to grain boundaries and the subsequent loss of grain boundary cohesive strength.
Figure 14b indicates that the fractured surface has predominantly transgranular fracture with mainly cleavage facets.
Plastic deformation because of slip, the process by which a dislocation moves in response to shear stresses, contributes to ductile fracture through crack propagation across the grain boundaries (transgranular).19 The fracture surface subsequent to this mechanism is commonly categorized by a dimpled configuration.
However, a lot of slag inclusions and transgranular cracks are produced at the same time, which may lead to the decline of mechanical properties.

Note the clear transgranular cleavage pattern with facet and flowery cleavages in Figure 4(c) at higher magnification.

Figure 14 shows grain boundary facets with cracks originating at grain boundary junctions alongside transgranular fatigue cracks, indicating build-up of time-dependent creep damage.
The weaker crystal particles will be broken to produce a transgranular failure with a lumpy surface.
Transgranular fracture is the predominant micro-cracking mode due to the existence of large graphite flakes (Figure 4(a)).
Typical example of the APC-SCC is the chloride SCC of austenitic stainless steel and transgranular (TG) type cracking.
