Dual-Phase steels (DP) are constituted by a ferrite matrix with a martensite fraction, giving a good combination of strength, ductility, capacity of energy absorption and strain hardening. Mechanical properties arecontrolled ...

In this work, the engineering stress-strain tensile curve and the force-deflection bending curve of two Dual-Phase (DP) steels are modeled, combining the mechanical data of fully ferritic and fully martensitic steels. The ...

The search for suitable materials for the transport industry, to meet more stringent regulations related to crashworthiness, emissions, and fuel economy led to the development of advanced high-strength steels (AHSS). Thermal ...

TRIP (Transformation Induced Plasticity) and DP (Dual-Phase) steels are written in a new series of steels which present excellent mechanical properties. As for microstructure aspect, TRIP steels consist on a ferrite matrix ...

In this work the microstructure generated in the Dual Phase steel by the Quench and Partition (T & P) treatment was evaluated. The heat treatment consists of heating the material at 740 ° C for a soaking time of 1h in ...

O desempenho dos aços multifásicos é estreitamente relacionado com seus microconstituintes. Assim, a caracterização e controle efetivo da microestrutura desses materiais são cruciais, sendo que os processos de ataques ...
