The γ→ε→α′ Martensitic Transformations in an Fe–Mn–C Alloy

The mechanisms of the fcc–bcc martensitic transformation revealed by pole figures

“…e ? a were previously observed in FeMnC and FeCrNi alloys [30][31][32][33][34] and have been described by Shimizu and Tanaka [33]. Let us explain the main basic mechanisms.…”

“…e ? a double step with retained e phase [33] and is well predicted by the invariant line criterion. The fact that only two a variants in R3 OR are found may be explained by strong variant selection mechanisms.…”

“…it is contracted by 2.4%. A shuffle of 1 6 ½1 10 a every two (1 1 0) a planes is necessary during the transformation [22,33]. There are two reported ORs for the classical bcc-hcp transformation: (Fig.…”

Martensitic transformation of pure iron at a grain boundary: Atomistic evidence for a two-step Kurdjumov-Sachs–Pitsch pathway

“…Thus in FeMnC and FeCrNi alloys [30][31][32] a two-step pathway via an intermediate hcp phase was identified. Also in theoretical work, transformation processes were proposed that involve an intermediate switching between various orientation relationships.…”

Nanocrystalline WC with non‐toxic Fe‐Mn binder

“…During a cooling Fe-Mn alloys poses also fcc => hcp martensitic phase transformation like cobalt. As it was shown in another works [9,10] Fe-Mn steels can be characterized by high wear resistance and it is probably that the same affect appear in WC-Fe/Mn composites. The damping capacity in Fe-Mn based alloys, what was reported in many works [11,12], is another advantage what in cutting tools applications is very important for cutting tools life.…”
