Obiettivo High-strength structural steels are characterized by a moderate YS/UTS ratio. Certain production processes, such as accelerated cooling, make it possible to obtain a steel with good weldability and high toughness properties. In view of the originality of the results of research conducted previously in the ECSC context and the keen interest they have aroused in industry, the proposed research is aimed at gathering further information in the field with a view to utilizing high-strength steels. To that end, the proposed concept, which involves predicting the fracture behaviour in the presence of a defect on the basis of typical properties determined systematically by the steel-maker, will be generalized in a wider framework. Attempts will be make to improve the method of forecasting critical defects using the Charpy V-notch impact strength and to extend its scope to tempered and self-hardened steels (with non-uniform structure) and welded assemblies. The possibility of extending these new concepts for the purpose of forecasting critical defects determined according to criteria other than that of generalized plastification will also be examined. The research will focus on structural steels or steels for high-strength tubes.
