... of American Iron and Steel Institute (AISI) 304 stainless steel. Scanning electron microscope examination of the fracture face reveals extensive microvoid coalescence, that is, ductile rupture, although the impact strength (at −196 °C, or −320 °F) was only 40% of that of a nonsensitized sample. The partially...
