“…The enhanced performance of DP rebars respect to TempCore® B450C was proved by comparing the residual values of the mechanical parameters achieved for the same corrosion entity, expressed in terms of mass loss (ML) referred to the exposed length. As widely presented in Caprili et al, 17 TempCore® B450C highlighted higher reduction of the mechanical properties: considering ML of about the 5%, the average residual deformation capacity (ResAgt) was respectively the 54% and the 70% of the uncorroded value for B450C and DPF steel reinforcing bars. Translating into numbers and considering the reference values presented in Table 1, this means that for initial Agt values, respectively, equal to 13.9% and 15.1% for DPF and B450C rebars, residual ResAgt up to 9.7% and 8.5% would be observed for ML equal to 5.0%.…”

“…The DP microstructure is achieved through a particular production process actually used only for flat or sheet products, making DP steels widely used in the automotive sector but strongly limited for civil structural and infrastructural applications. The production process (by hot‐rolling route or by the application of a post intercritical quenching treatment 17 ) leads to an undefined yielding stress–strain law with mechanical parameters—mainly in terms of hardening ratio—not always aligned with what required by actual standards for constructions (EN1998‐1:2005 7 ): if we look to common DP grades (like DP800 or DP1000) the ratio Rm/Re can be beyond the value of 1.35, upper limitation for ductility class “C” rebars.…”
