摘要

The combined requirement of higher strength and toughness in HSLA steels has led to the development of thermomechanical processes able to provide more complex microstructures. The constituents of these microstructures can intervene in different ways than those observed in conventional grades when brittle fracture processes are intended to shift to lower temperatures. This study considers the role of different microstructural features intervening in the cleavage process. For very low temperatures corresponding to the completely brittle behavior, the interaction between brittle constituents, as TiN particles and MA islands, with the surrounding crystallographic orientation of the matrix appears as the key factor.
