| Abstract: | In this paper the CCT diagrams for flash welding HAZ of rare-earth heavy rail steel are tested,influence of flash welding on microstructure and toughness of rail steel is studied. The results show that after flash welding toughness of course grain zone decrease and toughness of fine grain zone increase. |
