چکیده
In this article boron steel is analyzed on the example of steel grade B27. In view of the fact that steel is supplied in a state after hot rolling, and the choice of a suitable heat treatment is left to the buyer steel were examined after conventional heat treatments. Steel was studied in state as delivered, after normalization, after quenching and after quenching and tempering at different temperatures. Examinations of the basic parameters of strength, impact test and a tendency to brittle fracture, abrasion resistance and corrosion resistance were performed. The studies show big differences of the analyzed parameters depending on the applied heat treatment, which should provide guidance to users to specific applications of this type of steel.

A Study on the Mechanical Properties of Dual Phase Steels Prepared by the Direct and Step Quenching Procedure
Two different dual phase steels were prepared from low carbon manganese steel after the elimination of the banding using the direct quenching (DQ) and the step quenching (SQ) procedures. Different heat treatments resulted in different martensite morphologies, microstructures and mechanical properties. The heat treatments were designed in such a way to obtain a 0.25 volume fraction of martensite...
