The 500-1500% increase in the dissipated energy observed relative to the as-received material primarily comes from the change in the mode of failure from a smooth tension driven brittle fracture lo a torturous shear-driven ductile failure that frequently results in a sample that is only partially fractured, ihe characteristics of which are shown in Fig.
Upper bainitic microstructure could be an important alternative to the pearlitic microstructure because of perfect brittle fracture, no material loss and much more tough without sacrificing the brittleness.
