Effect of Intercritical Annealing on the Properties of Dual Phase Steel via Finite Element Method
نویسندگان
چکیده
Dual phase (DP) steels are rapidly becoming more and popular for automotive applications. They offer a weight reduction with combination of energy absorption crash zones. Rails, reinforcements, back panels, cross members, pillars can be given as application examples. DP microstructure consists soft ferrite matrix hard martensite islands. The islands provide strength while the ductile provides formability. level steel is related to amount in microstructure, arranged via intercritical annealing. In this work, thermodynamic analysis St52 was carried out Thermo-Calc software. A1 A3 temperatures were determined by calculating temperature-dependent fractions. Intercritical annealing according calculated critical (A1 A3). process modelled using Simheat NxT modelling simulation effect temperature on final hardness investigated.
