The effect of a constant tensile load on the hydrogen diffusivity in dual phase steel by electrochemical permeation experiments

, 2020
This work considers the effect of a constant load on the hydrogen diffusion characteristics studied by electrochemical permeation experiments. Dual phase steel and Armco iron are used for this purpose.

Effects of tempering on the mechanical and corrosion properties of dual phase steel

, 2020
The 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 ...

Ultrafine-grained dual-phase maraging steel with high strength and excellent cryogenic toughness

, 2021
A novel heat treatment route consisting of a low-temperature solution followed by an over-aging treatment at 500 °C is proposed to develop a high-strength, high-cryogenic-toughness maraging steel by forming an ultrafine-grained martensite (α′) and ...

Strain Hardening Behavior of Dual-Phase Steels

Metallurgical and Materials Transactions A, 2009
A 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.

Improved mechanical properties of V-microalloyed dual phase steel by enhancing martensite deformability

, 2020
A good combination of ultimate tensile strength (UTS) up to 1365 MPa and total strain to failure (StF) to 15.5 % has been achieved due to deformable martensite in the invented vanadium-microalloyed dual-phase (DP) steel, which was manufactured by two ...

Effects of the Phase Interface on Spallation Damage Nucleation and Evolution in Dual‐Phase Steel

Steel Research International, 2020
The dual‐phase steel sample obtained by step quenching (SQ) of AISI 1020 steel is shock loaded using one‐stage light‐gas gun experiments. The free surface particle velocity is measured by Doppler pin system (DPS) during the loading experiment. The effect

Hardenability of Austenite in a Dual-Phase Steel

Journal of Materials Engineering and Performance, 1999
A low-carbon, low-alloy steel was intercritically heat treated and thermomechanically processed to study the martensitic hardenability of austenite present. Rolling of the two-phase (α+γ) microstructure elongated austenite particles and reduced their martensitic hardenability because the α/γ interface where new ferrite forms during cooling was ...

The formability of dual-phase steels

Journal of Applied Metalworking, 1982
The formability of both heat-treated and as-hot-rolled dual-phase steels was evaluated in neck- and fracture-limited forming modes and compared with the formability of conventional high-strength low-alloy (HSLA) or microalloyed steels. For both production routes the formability of dual-phase steels was found to be sensitive to tensile strength ...
