Atomic-scale observation of hydrogen trap sites in bainite–austenite dual-phase steel by APT

, 2021
It 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 ...

Investigation on micromechanism involved in ferrite hardening after prestraining of dual-phase steel

, 2021
The evolution of low angle grain boundaries (LAGBs) and Taylor factor (TF) was investigated by EBSD analysis to reveal the micromechanism of ferrite hardening for dual-phase steel during prestraining from 1% to 5%.

A new method to produce dual-phase steel

, 2021
In 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).

Properties of Dual Phase Steels

Materials Testing, 2003
Two 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.

Fatigue of a dual- phase steel

Metallurgical Transactions A, 1979
A study has been made of the fatigue of a V containing dual-phase steel, whose tensile strength is equivalent to that of SAE 980X high strength, low-alloy (HSLA) steels, as a function of prestrain. It is found that the cyclic stress-strain curve, strain-life response and notch sensitivity are little affected by pre-strains of up to 8 pct: This is in ...

Formability of Dual-Phase Steels

JOM, 1982
The 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.
