    Abstract

    The lack of design rules limits the application of VHSS. One critical point limiting their use lies in their poorly documented low temperature fracture properties in relation to more conventional steels. The two major concepts governing the assessment of steels construction codes are the Master Curve methodology and the T0-TCV28J transition temperature correlation. Focusing on novel directly quenched high performance steels, the applicability of the Master Curve methodology with special emphasis on the low temperature region is investigated and the validity of the standard T0-TCV28J transition temperature correlation is checked. Improvements to the criteria are proposed for further considerations.
