Enhancing the yield strength of intercritically annealed Q&P steel via bainite-based quenching and partitioning treatment

Journal of Materials Research and Technology, 2023
Intercritically annealed Q&P steels exhibit good strength-ductility synergies. Unlike fully austenized Q&P steels, intercritically annealed Q&P steels exhibit good ductility but contain a significant amount of ferrite, resulting in a lower yield strength

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

steel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...

Phase Transformation Behavior of Continuously Cooled Fe–C–V–(Mo) Alloys

steel research international, Volume 97, Issue 11, Page 5475-5484, November 2026.
Additions of vanadium and molybdenum microalloying are shown to reshape phase transformations in clean low‐carbon steels. By tracking microstructural shifts during continuous cooling, the work uncovers the correlation between transformation kinetics, ferrite morphology, and hardness.
