“…This is because DP steels are composed of different phases, with martensite as the hard phase and ferrite as the ductile soft phase 2 . The martensite phase is dispersed within the ferrite matrix, resulting in a material that is both strong and ductile, making it ideal for applications that require high strength and good formability 3,4 . DP steel possesses excellent mechanical qualities such as high tensile strength, improved formability, continuous yielding behavior, crashworthiness, high strength-ductility, and high work hardening rates, which make it a reliable and affordable material for the manufacturing sector, including welding [5][6][7][8] .…”

Dual-phase steel is characterized by good strength and hardness with high ductility. This type of steel has a wide range of uses in the modern-day industry, especially in the automobile industry. This paper reports an experimental study ofthe effect of intercritical annealing parameters such as temperature and soaking time on hardness. The Taguchi method based on L9 was used with a temperature range from 750 ⁰C to 800 ⁰C and a soaking time range from 30 min to 60 min. All samples were treated in the furnace at a specified temperature and soaking time quenched in water. It is observed that the hardness increases with increasing the intercritical temperature and soaking time. On the other hand, temperature has a significant effect more than soaking time on the hardness.
