Yield stress and strain‐rate data were obtained in compression at various temperatures. Niobium single crystals were tested both in the irradiation and unirradiated condition. The neutron irradiation largely affected the athermal component of the flow stress, however, it also induced a smaller but measurable increase in the thermal component of stress. The data indicate that increasing solute content effects an athermal strengthening similar to that of neutron irradiation.
