Simultaneous Improvement of Strength and Ductility of Dual-Phase Steel Processed by Multi-Step Cyclic Rolling and Intercritical Annealing. [PDF]
Materials (Basel), 2022 In the present study, a multi-step (MS) cyclic rolling and intercritcal annealing process was proposed and applied for dual-phase (DP) steel. The MS process performed three times with 27% deformations and intercritical annealing, while the single-step ...

Quenching and Partitioning of Multiphase Aluminum-Added Steels
Metals, 2019 The quenching and partitioning response following intercritical annealing was investigated for three lean TRIP-type high-Al steel compositions. Depending on the intercritical austenite fraction following annealing, the steels assumed either a ferrite ...

Intercritical annealing treatment of PHS2000 and study of its microstructure and properties
Journal of Physics: Conference Series, 2022 Abstract Dual-phase steel (also known as DP steel) is the most widely used ultra-high-strength steel in automobile covering parts and structural parts. Since the concept of automotive lightweight has been put forward and deepened, the development of higher strength grade DP steel and the study of its microstructure and properties are of ...
