Irradiation hardening of pure tungsten exposed to neutron irradiation [PDF]
Journal of Nuclear Materials, 2016 Abstract Pure tungsten samples have been neutron irradiated in HFIR at 90–850 °C to 0.03–2.2 dpa. A dispersed barrier hardening model informed by the available microstructure data has been used to predict the hardness. Comparison of the model predictions and the measured Vickers hardness reveals the dominant hardening contribution at various ...
