Deformation and fracture
WebMar 10, 2024 · A poor ductility due to brittle fracture without plastic deformation was observed in steel QU. The engineering stress–strain curves presented a continuous yielding phenomenon in steels T250, T300, and T400, which could be related to a large number of mobile dislocations in the microstructure.
