Development of microstructure and texture in Fe–26Mn–3Si–3Al alloy during cold-rolling and annealing

Microstructure And Texture Evolution During Cold-Rolling In The Fe-23Mn-3Si-3Al Alloy

“…Some research has indicated that such alloys reveal mainly the TRIPeffect when the manganese contents are lower than 15%, while the TWIP-effect is dominant when manganese contents are higher than 25%. For manganese contents between 15% and 25%, both of the effects coexist [10,[12][13][14][15].…”

Analysis of Texture and Microstructure of Annealed Fe-23Mn-3Si-3Al Steel

“…The relation between the phases γ and ε is referred to as the Shoji-Nishiyama relationship (S-N) {002}ε {111}γ and 110 ε 110 γ [10]. Such a correlation was reported also in other papers devoted to high-manganese steels [5,6,11].…”

“…They possess very good functional properties as far as combination of strength and plasticity is concerned [1]. In these alloys, plastic deformation may take place by twinning (the TWIP effect -twinning induced plasticity) or a martensitic transformation induced by deformation (the TRIP effect -transformation induced plasticity) [1][2][3][4][5][6]. In numerous cases both of those effects may occur simultaneously.…”

Phase Decomposition in a High-Manganese Steel

“…In recent years, intensive research has been conducted into high-manganese steels having various chemical compositions (Mn, Al, C, and Si). An important feature of high-manganese steels is a substantial reserve of plasticity, and that means the ability to absorb energy in the course of a collision, which improves safety of passengers [1][2][3][4][5][6][7][8][9].…”
