Steels with medium manganese (Mn) content (3∼ 12 wt-%) have emerged as a new alloy
class and received considerable attention during the last decade. The microstructure and …

We highlight the recent advance in strong transformation-induced plasticity (TRIP) steels,
which have higher alloying contents compared to the conventional TRIP steels for achieving …

We elucidate here the impact of grain size and manganese concentration on the austenite
stability and the deformation behavior of a cold-rolled transformation-induced plasticity …

After summarizing the relevant researches on the medium Mn steels in references, two new
targets on the tensile properties have been defined. One is that both transformation-induced …

The development of materials for automobile applications, especially for the body in white,
results from multiple and often contradictory constraints: a search for lightness, a high …

Medium Mn steels have been actively investigated due to their excellent balance between
material cost and mechanical properties. The steels possess a single α′ martensite phase …

Adding a large amount of light elements such as aluminum to steels is not a new concept
recalling that several Fe–Al–Mn–C alloys were patented in 1950s for replacement of nickel …

The effects of the initial microstructure of α′ martensite on the microstructural evolution
during intercritical annealing and the tensile properties of annealed specimens were …

A heterostructured medium Mn steel with duplex phases (ferrite and austenite) and multiple
morphologies (lath-typed and granular) is fabricated by a novel two-stage warm rolling …

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 …
