Mechanical Behaviour of Dual Phase Steels under Different Strain Rates [PDF]
Kemija u Industriji, 2023 The objective of this research was to analyse the stress and strain behaviours of the triaxiality specimens (specimens of different shaping) of dual-phase steels, respectively DP600 and DP800, whose microstructures mainly comprise ferrite and martensite ...

FIBRE LASER WELDING OF DUAL PHASE STEELS
Acta Metallurgica Slovaca, 2015 The fibre laser welding of two different dual phase steels HCT980X and HCT600X was evaluated. The sheets with thickness of 1.2 mm were welded using the solid-state fibre laser IPG type YLR 4500 with maximum output 4.5 kW and wave length 1060 nm at ...

Production and characterization of dual-phase steels from an AISI 8620 steel with high Mn content
Dyna, 2021 Dual phase steels are materials whose microstructure is composed of a ferrite matrix with martensite islands. Ferrite provides excellent ductility, while martensite increases the strength of steel, this provides a special appeal in the automotive ...

Bauschinger effect and coercivity in dual-phase steels
Chinese Physics Letters, 1984 Initial flow stresses and coercivities during and after tension and tension plus compression in ferrite-martensite dual phase steels have been measured. It was found that both parameters for tension plus compression are smaller than those for tension only. For the flow stress, this phenomenon is called Bauschinger effect.
