Project

Competition of the transgranular and intergranular mechanism at the brittle fracture initiation in the structural steels (GA106/98/P090)

Local characteristics of fracture should be analysed for steel displaying competition of transgranular cleavage fracture mechanism and intergranular mechanism. Criteria based on critical fracture stress ar...
