Enhanced mechanical properties of dual phase steel via cross rolling and intercritical annealing
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2021Cross rolling followed by intercritical annealing was proposed as an alternative route for processing of dual phase (DP) steels, which led to fine recrystallized ferrite grain size and uniformly distributed martensite islands.

Austenite formation during intercritical annealing
Metallurgical and Materials Transactions A, 2004A systematic experimental study has been conducted on ferrite recrystallization and intercritical austenite formation for two low-carbon steels with chemical compositions typically used for dual-phase and transformation-induced plasticity (TRIP) steels.

Recrystallisation at Intercritical Annealing in Low Carbon Steels
Materials Science Forum, 2007Subgrain growth in deformed ferrite and incomplete recrystallisation during intercritical annealing in low carbon (LC) steels was investigated by EBSD and FEGTEM/EDS. It was confirmed that fine dual phase (α+γ) microstructures could be obtained even without the addition of microalloying elements such as Nb and Ti, if the steels were heated above Ac1 ...

Retained austenite in intercritically annealed HSLA steel
Metallography, 1987Abstract The effects of processing parameters on austenite retention in intercritically annealed HSLA steels have been investigated. Low-temperature tempering was found to be necessary for successful tint etch of high-carbon martensite in dual-phase structure with sodium metabisulfite.

Microstructure and mechanical properties of medium manganese steel in intercritical annealing
Materials Science and Technology, 2023A new type of cold-rolled medium manganese steel was investigated. The test steel was treated by Q&P process. With the increase in annealing temperature, the grain size gradually increases, the carbides dissolve progressively and the fine lath grains transform into massive or equiaxed grains.

Benefits of Intercritical Annealing in Quenching and Partitioning Steel
Metallurgical and Materials Transactions A, 2018Compared to the quenching and partitioning (Q&P) steel produced by full austenization annealing, the Q&P steel produced by the intercritical annealing shows a similar ultimate tensile stress but a larger tensile ductility. This property is attributable to the higher volume fraction and the better mechanical stability of the retained austenite after the

The so-called bimodal microstructure of Ti-6Al-4V alloy, composed of primary α grains (αp) and transformed β areas (βtrans), can be regarded as a “dual-phase” structure to some extent, the mechanical properties of which are closely related to the sizes ...

Ferrite-Martensite Band Formation During the Intercritical Annealing
Journal of Materials Engineering and Performance, 2015Microstructural evolution during the intercritical annealing at 740 and 770 °C for 120-900 s in a low-carbon low-alloy steel from the initial martensitic matrix was studied by electron microscopy equipped with energy dispersive x-ray spectroscopy and x-ray diffraction.
