    The Master Curve methodology is a statistical, theoretical, micromechanism based, analysis method for fracture toughness in the ductile to brittle transition region. The method, originally developed at VTT Manufacturing Technology" simultaneously account for the scatter, size effects and temperature dependence of fracture toughness. The method has been successfully applied to a very large number of different ferritic steels and it forms the basis of the ASTM testing standard for fracture toughness testing in the transition region. The Master Curve (MC) methodology has evolved from only being a brittle fracture testing and analysis procedure to a technological tool capable of addressing many more structural integrity issues like constraint and parameter transferability. Here, some recent advances of the technology are presented. The advances include eg. constraint adjustment, description of warm pre-stress effects, analysis of inhomogenous materials and assessment of real three-dimensional flaws.
