The impact toughness of non-treated and irradiated 12Cr1MoV steel Charpy specimens has been studied in the range of temperatures from 20 C to 600 C. It was revealed that the ion beam treatment of steel deteriorates the impact toughness by 5–40 % at the tested temperature range. The physical regularities of irradiation effect on microhardness and hardness of the treated surface were investigated. It was also found out that irradiated specimens fracture via more brittle mechanism, which is related to both more severe stress–strain state at the notch tip and gradient alteration of properties in the subsurface layer.
