Abstract: A series of model alloys are studied to understand irradiation embrittlement phenomena and similitude in behaviours with commercial reactor pressure vessel materials. Important results and prediction models for ductile-to-brittle transition temperature shift are drawn from the data. Some of the issues have always been the lack of tensile properties and the impossibility to establish a correlation between the transition temperature and the hardening of the alloys. Recently, within the FRAME project, tensile properties have been measured on both fresh and irradiated specimens. It is these new data that are analysed in this paper to investigate the irradiation-induced yield strength increases of model alloys and compare them with existing data from reactor pressure vessel steels.
