Deformation-Induced Transformation of Retained Austenite in Transformation Induced Plasticity-Aided Steels: A Thermodynamic Model

“…[21] The yield stress for slip in austenite decreases with increasing temperature and above M S r , the stress needed to initiate martensite transformation is large enough to cause plastic deformation (by slip) in austenite. [22] At temperatures higher than M S r , martensite transformation takes places in a plastically deformed austenite on new nucleation sites generated by plastic deformation and at stresses that are considerably lower than is expected from a simple extrapolation of the critical stress-temperature line between M S and M S r ( Figure 2). [20] This mode of transformation is termed strain-induced transformation.…”

Overview of Dynamic Strain Aging and Associated Phenomena in Fe–Mn–C Austenitic Steels

“…1 are attributed to DSA, serrations in FCC alloys can be caused by other metallurgical factors such as deformation twinning, 17) dynamic precipitation, 3,18) and martensitic transformation. [19][20][21] Therefore, we must carefully check deformation microstructure characteristics and temperature dependence of stress-strain response when serrations are correlated with DSA. 2 The dislocation density in Eqs.…”

Stress-Induced Martensitic Transformation Behaviors at Various Temperatures and Their TRIP Effects in SUS304 Metastable Austenitic Stainless Steel

“…[1][2][3] Thus far, the TRIP effect has been investigated for metastable austenitic stainless steels, [3][4][5][6][7][8][9][10] 9% Ni steels, 11) and TRIP-aided multi-microstructure steels. [12][13][14] In the previous studies, various important factors that influence stress-induced transformations, 1,[3][4][5][6][7] kinetics of transformations, 3,12) and mechanical properties in prediction models for TRIP 8,14,15) have been investigated.…”
