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 mechanical properties of dual phase steels typically have low yield strength and high strain hardening rate, high ultimate strength, high ductility and bake hardening at the paint baking temperature (∼170 °C) [188]. Another major advantage of the dual-phase steels is their good formability [15,357,369]. Low carbon dual phase steels also ...

2014年8月18日 · DP steels have a unique combination of outstanding elongation and work hardening rate, providing them superior ultimate tensile strengths when compared to traditional steels of same yield strength. The comparison of the engineering stress-strain graph for the DP steel and HSLA steel of same yield strength is illustrated in Figure 3.
ArcelorMittal offers a full spectrum of dual phase (DP) steels with tensile strength levels ranging from 500 to 1180 MPa. Dual phase steels are one of the important new advanced high strength steels (AHSS) developed for the automotive industry.
Dual Phase Steel - an overview | ScienceDirect Topics
Dual-phase (DP) steels are composed of ferrite and 5–20% of martensite, and their strength ranges from 500 to 1200 MPa. DP steels have a microstructure of mainly soft ferrite, with islands of hard martensite dispersed throughout. The strength level of these grades is related to the amount of martensite in the microstructure.
Dual Phase - AHSS Guidelines
Dual Phase (DP) steels have a microstructure consisting of a ferritic matrix with martensitic islands as a hard second phase, shown schematically in Figure 1. The soft ferrite phase is generally continuous, giving these steels excellent ductility.
Dual-Phase Steels: An Introduction - National Material
2018年3月23日 · Dual-Phase steels (DP steels) are a part of the Advanced High Strength Steel (AHSS) family. Ferrite-Martensite dual-phase steel is a low-to-medium carbon material with between 5-50% volume fractional martensite islands that are dispersed in a soft ferrite matrix.
What are Dual Phase Steels? Properties, Composition » BorTec
Dual-phase steel (also known as DP steel, ferritic-martensitic steel, or two-phase steel) is a type of high-strength steel characterized by its unique combination of ferritic (soft) and martensitic (hard) microstructures.
Dual-phase (DP) steel is the flagship of advanced high-strength steels, which were the first among various candidate alloy systems to find application in weight-reduced automotive components.
