In Situ Investigation of the Iron Carbide Precipitation Process in a Fe-C-Mn-Si Q&P Steel [PDF]
Materials, 2018 Quenching and Partitioning (Q&P) steels are promising candidates for automotive applications because of their lightweight potential. Their properties depend on carbon enrichment in austenite which, in turn, is strongly influenced by carbide precipitation in martensite during quenching and partitioning treatment.

Two-loop QCD-EW master integrals for Z plus jet production at large transverse momentum
Journal of High Energy Physics, 2020 The production of electroweak Z bosons that decay to neutrinos and recoil against jets with large transverse momentum p ⊥ is an important background process to searches for dark matter at the Large Hadron Collider (LHC).

Strength–Toughness of a Low-Alloy 0.25C Steel Treated by Q&P Processing
Materials, 2023 Quenching and partitioning (Q&P) treatments were applied to 0.25C steel to produce the microstructures that exhibit an improved balance of mechanical properties. The simultaneous bainitic transformation and carbon enrichment of retained austenite (RA) during the partitioning stage at 350 °C result in the coexistence of RA islands with irregular ...
