Pearlitic steels aged at 300°C and 450°C after cold-drawing were used. Both tensile deformed and subsequently fractured samples were prepared by slow strain rate tests (SSRT) with and without cathodic hydrogen charge. Average positron lifetime increased with increasing tensile strain both in the case of the 300°C-aged and 450°C-aged steels.
Fluorine and nitrogen are important elements of metallurgical slags and fluxes. Studies on their viscosity have often focused on the additive effect of fluoride and nitride compounds (e.g., CaF 2 and Si 3 N 4), whereas the influence of anionic composition (i.e., oxygen, fluorine and nitrogen concentrations) with a fixed cationic composition remains unclear.
