11756 Fatigue fracture and intergranular fracture
modes observed 10388 Intergranular fracture
Intergranular fracture is typical of many forms of SCC, hydrogen embrittlement, and temper-embrittled steel.
Plastics do not display cleavage and intergranular fracture.
The intergranular fracture indicated a brittle failure mode and that the material had become embrittled.
The large grain size, the intergranular fracture, and chromium carbide precipitation pointed toward the material being significantly weakened or embrittled due to improper heat treatment.
A Computational Model for Intergranular Fracture
in Nanocrystalline and Ultra-Fine Polycrystalline Metals
Eversince aluminum (Al) has been used as a deoxidizer for steel, foundrymen have seen the occasional occurrence of a brittle, intergranular fracture
mode in castings.
