The work demonstrates that changes in Charpy V-notch impact properties can be monitored by microhardness measurements for radiation-embrittled ferritic steels in the transition region. A qualitative basis for understanding this relationship is developed from extension of existing models for lower-shelf fracture toughness and analysis of the shifts in the ductile-to-brittle transition temperature with changes in the yield strength. Microhardness is shown to correlate with the yield stress of the irradiated ferritic materials described in this report. A comparison of Charpy energy and yield stress data suggests that, for the purposes of this analysis, the fracture stress is insensitive to both irradiation and annealing in the transition region.
