Mechanical properties and structure of refractory metal base alloys exposed to neutron irradiation
AbstractAbstract
[en] The effect of neutron irradiation on mechanical properties and the structure of the V-2.5, Zr-0.35C, Nb-I Zr-0.1C and Mo-0.11 Zr-0.002B alloys has been investigated at 730-1070 deg C and (1.3-1.8) 102 n/cm2 (> 0.1 MeV). It is shown that under these conditions the irradiation results in intense softening of the V-Zr-C alloy and hardening of the Nb-Zr-B and Mo-Zr-B alloys, whereas a minimum yield strength increase of two latter alloys is observed in the radiation temperature range 0.43-0.45 Tsub(m). Reasons for appreciable irradiation-induced enhancement of V-Zr-C softening are established. It is shown that the minimum softening of the Mo-Zr-B alloy at temperature of 0.43-0.45 Tsub(m) is due to suppressing void formation at these temperatures. Properties of vanadium, niobium and molybdenum alloys exposed to neutron irradiation are discussed
