Abstract

The grain-boundary structure of the ferritic component of boiler pipes made of steel 20 manufactured by pressing and hot rolling technologies was investigated, and special boundaries of Σ = 3 were discovered according to the concept of lattices of coinciding nodes. In the pipes obtained by hot pressing technology, the number of special boundaries is much larger (up to 14.3%) than in hot-rolled (up to 3.7%).
