Fracture toughness of 15Kh2MFA and 15Kh2NMFA steel welded joints at repeated heating temperature

Creators

Description

Tests of welded samples made of 15Kh2MFA and 15Kh2NMFA vessel steels were carried out in the temperature range of stress-relief annealing. It is established that all samples were fractured in weld metal. It marked that at 550-600 C the most unfavourable combination of minimum brittle strength and the relaxation velocity of residual stresses is created. Parameters of fracture thoughness of steels investigated have similar values
