Dorofeev, Yu. Dybov, S. Egorov] Conclusions: In joining of carbon steels in the zone of former contact there occurs a white band which is tentatively identified as ferrite, which has a significant influence on the mechanical properties of the joint. The strength characteristics of the zone of joining of low- and medium-carbon steels reach the level of properties corresponding to a monolithic material with a deformation temperature of not less than 950°C and a degree of deformation of not less than 30%. The relative reduction is within limits of 2-15%. Fractographic analysis showed that fracture occurs in the ferritic band. The reason for formation of the ferritic band must be assumed to be preferential precipitation of excess ferrite in this area in cooling as the result of occurrence of micropores and and nonmetallic inclusions, which are embryos of the new phase. It was established that the ferritic band is distinguished by higher microhardness than the ferrite of the matrix of the steel.
