A new method to produce dual-phase steel
, 2021In the current research, a new dual-phase (DP) steel produced by a novel technique consists of a combination of friction stir welding (FSW) and austenitization treatment using two different low carbon steels (interstitial free (IF) and St52).

Atomic-scale observation of hydrogen trap sites in bainite–austenite dual-phase steel by APT
, 2021It was reported by the thermal desorption analysis (TDA) of hydrogen that bainite–austenite dual-phase steels showed two activation energies of ~30 kJ/mol and ~ 47 kJ/mol under low- and high-fugacity conditions, respectively, and the latter energy ...

Microstructures of dual-phase steels are made up of mostly ferrite along with some bainite or martensite. An alloy was designed theoretically to produce a similar microstructure directly during cooling after solidification. Although the dual-phase microstructure was achieved, the tensile properties of the cast alloy were found not to be satisfactory ...

Dual Phase Steel Production Bumpers
SAE Technical Paper Series, 1979<div class="htmlview paragraph">The use of HSLA dual phase steel is an effective method of reducing bumper weight while meeting ever increasing government performance requirements. A paper analysis, followed by a hardware evaluation, successfully substituted “dual phase” for conventional HSLA steel at a reduced thickness.

Formability of Dual-Phase Steels
JOM, 1982The mechanical behavior of dual-phase steels depends on a broad range of metallurgical phenomena. The initial hardening reflects the volume fraction of the martensitic phase via a back stress, but this also depends on the local strength of the martensite.

Strain Hardening Behavior of Dual-Phase Steels
Metallurgical and Materials Transactions A, 2009A detailed qualitative and quantitative examination of the microstructure and mechanical properties of three different classes of DP600 and DP450 dual-phase (DP) steels was carried out. The tested DP steels are characterized by different alloying elements: aluminum, boron, and phosphorus.

Effects of tempering on the mechanical and corrosion properties of dual phase steel
, 2020The mechanical and corrosion behaviors of low carbon dual phase (DP) steel were studied based on different tempering conditions. By increasing the time and temperature of tempering, the ultimate tensile strength (UTS), the hardness, and the corrosion ...

Properties of Dual Phase Steels
Materials Testing, 2003Two different heat treatment (intercriticaly and intermediate heat treatments) have been applied to steels containing 0.16% C in order to obtain dual-phase steels (DPS) with different microstructures. One set of intermediate quenched samples were tempered.
