Quantitative correlation of fracture toughness and microstructure for high strength steels and their welds

Objectif

Fracture mechanics methods take account of the quantified toughness and hence allow for safe and economical design. Especially, fracture toughness values are often missing and are expensive to obtain. The aim of this project is to apply a newly developed method of correlation between microstructural parameters and fracture toughness allowing for an economical alternative of obtaining fracture toughness values directly after steel has been produced. This offers steel producers an additional opportunity of characterisation of the steels during production and development of new grades respectively. Within the project the four steel grades S 355, S 460, S 690 and S 890, among them different heat treatments and different toughness levels, will be investigated. Welds of these steels will be included. Special attention will be given to quantitative examination. Crack initiation and growth will be analysed.
