摘要：
The influence of heat treatment of a welded joint from austenitic steel 12Cr18Ni10Ti on the microstructure and resistance to intergranular corrosion, which was determined according to GOST 6032–2003 (AMU method), was evaluated. It was found that heat treatment according to the two modes used has an effect on the microstructure. After testing for intergranular corrosion and three-point bending cracks or damage in the welds with heat treatment is not observed. The seams are highly resistant to intergranular corrosion. The weld seams without heat treatment also did not have intergranular damages due to a slight dissolution of titanium carbides in austenite and the absence of chromium carbides along the grain boundaries. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
