This research deals with the relationship between the microstructural features and the susceptibility to brittle fracture of six selected commercially produced ultra-high strength steels. The parameters selected for the susceptibility to brittle fracture were the susceptibility to plastic instability, indicative of the susceptibility to ductile fracture initiation, and controlled total available energy bend test to determine the conditions for acceleration of crack propagation and the energy absorbed in rapid crack propagation. The microstructures were studied by standard techniques of optical microscopy, electron microscopy, and electron diffraction.
