Vanadium Precipitation During Intercritical Annealing in Cold Rolled TRIP Steels
ISIJ International, 2007 Flat carbon steel manufacturers are currently developing new TRansformation Induced Plasticity (TRIP) steels as a response to strong demands for vehicle lightening and security reinforcement from the automobile sector. Compared to conventional high strength steels these advanced grades exhibit a very favourable compromise between strength and ductility

Tailoring the deformation behaviour of a medium Mn steel through isothermal intercritical annealing
Materialia, 2022 A novel concept of varying the strain hardening rate of a medium Mn steel with 8 wt\% Mn by varying the duration of the intercritical anneal after hot rolling was explored. It was found that the stability of the austenite phase showed an inverse square root relationship with intercritical annealing duration and that the maximum strain hardening rate ...

Materials and Corrosion, Volume 76, Issue 10, Page 1478-1496, October 2025.This study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel. Hydrogen charging reduced the ductility of all specimens. Both subcritical annealing and cold working decreased somewhat the degree of HE.

Materials Genome Engineering Advances, Volume 3, Issue 3, September 2025.This study proposes a novel high‐throughput experimental method integrating gradient heat treatment and advanced characterization techniques. This method can efficiently establish the processing–microstructure relation in quenching and partitioning steels. As quenching temperature decreases, the fraction of retained austenite initially increases due to
