Over many decades, significant efforts have been made to improve the strength-elongation
product of advanced high strength steels (AHSSs) by creating tailored multi-phase …

In this review, we separate the different governing factors on austenite stability into intrinsic
and extrinsic factors, depending on the domain defined by austenite grain boundaries. The …

Here the effect of retained austenite stability and martensite-austenite island/fresh
martensite on mechanical properties, fracture behavior, and corrosion resistance of 0.5 wt …

The mechanical and thermal stability of austenite in multiphase advanced high strength
steels are influenced by the surrounding microstructure. The mechanisms underlying and …

Abstract A Quenching-Austenite Reversion Treatment (Q-ART) is used to process an Fe-0.2
C-8Mn-2Al (all in wt.%) medium Mn steel to investigate the effect of pre-existed austenite on …

The evolution of the dislocation densities in martensite and in austenite during the quench of
a low-carbon (0.215 wt% C) steel is investigated in situ by the mean of a High Energy X-Ray …

It is found that the optimum mechanical properties of Q&P steels are not necessarily
obtained when the volume fraction of retained austenite is maximum, but they can be …

We made the chemical heterogeneity in steel consisting of mostly martensite with retained
austenite by applying intercritical annealing prior to full austenitization. It enables …

In this study we explored mechanisms for improving the mechanical properties and retained-
austenite (RA) stability of a Q&P steel by adjusting the phase ratio. With increasing …

Martensitic transformation is accompanied by the generation of microscale and macroscale
internal stresses during cooling below the martensitic transformation start temperature …
