The influence of primary structure and strain conditions on the mechanical properties of smooth-rolled bars

摘要

In this paper, were made studies which aim was to correlate the microstructure obtained with the mechanical properties of finished hot-rolled smooth bars. The mechanical properties of finished products is the result of microstructure obtained during the plastic working processes. The research has shown that the impact of primary structure in combination with increased share of perlite result in a large decrease in the mechanical properties of impact energy in particular. To the researches were used optical microscopy and scanning electron microscopy.
