Dual-phase steel - Wikipedia

Dual-phase steel (DP steel) is a high-strength steel that has a ferritic–martensitic microstructure. DP steels are produced from low or medium carbon steels that are quenched from a temperature above A 1 but below A 3 determined from continuous cooling transformation diagram.

Dual Phase Steel - an overview | ScienceDirect Topics

The production of dual phase steel is similar to that of TRIP steel except that the steel is alloyed and cooled from the intercritical temperature range in such a way as to avoid the formation of bainite. The final micro-structure consists of ferrite and martensite.[PDF]

Dual Phase steels - automotive.arcelormittal

Dual Phase steels can be drawn on conventional tools, provided the settings are properly adjusted. For example, drawing pressure should be increased by approximately 20% for a Dual Phase 600, compared to a micro-alloyed (HSLA) type steel of the same thickness.[PDF]

Dual Phase Steels - automotive.arcelormittal

ArcelorMittal produces two types of dual phase steel. The DI-FORM™ grades are conventional DP steels with low yield-to-tensile-strength ratios. The HI FORM (HF) grades use additional solid solution strengthening in the ferrite

Dual-phase steels (DP steels ... Grain refinement in dual phase steel In ultrafine single phase alloys it has been shown that the increase in yield stress is accompanied by a decrease in the work hardening rate, which is responsible for poor ductility.

TRIP steel - Wikipedia

TRIP steel are a class of high-strength steel alloys typically used in naval and marine applications and in the automotive industry. TRIP stands for "Transformation induced plasticity," which implies a phase transformation in the material, typically when a stress is applied.Microstructure·

Dual Phase Steels | ispatguru

Dual Phase Steels The term dual phase steels, or DP steels, refers to a class of high strength steels which is composed of two phases namely a purely ferrite matrix and a dispersed second phase of martensite (5 % to 30 %).In addition to martensite, small amounts of bainite and residual austenite may exist. DP steels were developed in the 1970s.
