...). An additional fracture mode, very often identified in cast iron failures, is quasi-cleavage. Each fracture mode has a distinctive crack propagation mechanism. Dimple rupture is typical of ductile metals that fail as the result of nucleation, growth, and coalescence of microscopic voids that initiate...
