Description

Radiation hardening and radiation embrittlement were studied of a welded joint made using a submerged arc automatic welder with an asymmetric gap, of a CrNiMoV steel type 15Kh2NMFAA. Two different filler wires were used in welding. The specimens were irradiated with a fluence of 9.3 x 1023 n.m-2 at E>0.5 MeV. The results of the experiments show that under certain, not quite accurately defined conditions, significant embrittlement can occur of the weld metal during the CrNiMoV steel welding, this due to the effect of segregation or microsegregation of impurities in tempering embrittlement. The trends are suggested of further research that should eliminate this danger. (Z.M.). 2 figs., 2 tabs., 18 refs
