Intergranular fracture is also a common fracture mode observed for both tempered martensite embrittlement in plain carbon steels and temper embrittlement in alloy steels in the presence of phosphorus.

Thus, the predominance of tensile ratcheting in the crack propagation phase highlighted two failure modes: time-dependent intergranular fracture and stress-dependent ductile rupture.
Intergranular fracture was observed only in areas with relatively high amounts of ferrite (Figure 4(b)).
Fractographic studies were performed to determine the maximum portion of brittle intergranular fracture ([eta]) in the fracture surfaces of Charpy specimens after impact tests, which correlates with the level of phosphorus concentration in grain boundaries of the material.
