Corrosion behaviour of dual‐phase and galvanized steels in concrete [PDF]

Anti-Corrosion Methods and Materials, 2012
Purpose: The purpose of this paper is to present results of an evaluation of dual-phase and galvanized steel reinforcements in corrosive environments. Design/methodology/approach: Low carbon steels were intercritically annealed at 740°C followed by water

Nitrogen in HSLA and dual phase steels [PDF]

, 1989
Nitrogen is universally present in all steels, and although its solubility under normal steelmaking conditions is small it can exert large effects on steel properties. Some of these effects are detrimental, often being associated with various embrittlement phenomena.

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.

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 ...

The formability of a dual phase steel

Metallurgical Transactions A, 1981
The mechanical properties and the forming behavior of a dual phase sheet steel have been assessed. The effect of downgaging on forming properties was especially considered because of its importance in lighter weight, energy saving materials. A lower bound method has been used to determine the forming limit diagrams of the steel. Results have shown that
