Effect of Alloying with Aluminum and Deformation-Heat Treatment on Rolled Product Crystal Structure

Resumo

Ferritic steels with high aluminum content are studied experimentally. A feature of the hot-rolled condition of steels alloyed with more than 5% aluminum is formation of fine dislocation cellular substructure. It is shown that with an increase in aluminum content and decrease in final rolling temperature the cellular substructure becomes more pronounced, which leads to an improvement of rolled product strength properties.
