Fe–23wt.%Mn–3wt.%Si–3wt.%Al alloy was cast, homogenized at 1150ºC, hot-rolled at temperatures between 1200ºC and 900ºC and next cold-rolled from 5% up to 40% reductions in thickness. Microstructure and texture of this alloy, which has a low stacking fault energy, were defined after cold-rolling. Investigation of transmission electron microscopy and X-ray diffraction showed that mechanical twinning and martensitic transformations (γ_fcc→ε_hcp and γ_fcc→ε_hcp→α′_bcc) took place during cold-rolling. The crystallographic Shoji-Nishiyama (S-N) {00.2}ε║{111}γ, <11.0>ε ║ <110>γ and Kurdjumov-Sachs (K-S) {111}γ║{101}α’, <101>γ║<111>α’ relations between martensite (ε, α’) and austenite (γ), were found in the coldrolled material.

W artykule zamieszczono wyniki badań mikrostruktury i tekstury otrzymane dla stopu Fe–23%Mn–3%Si–3%Al (% masowe). Po odlaniu wlewek homogenizowano przy temperaturze 1150ºC, walcowano na gorąco w zakresie temperatur 1200ºC-900ºC i następnie walcowano na zimno do odkształceń od 5% do 40%. Wyniki badań uzyskane przy użyciu transmisyjnej mikroskopii elektronowej i metod dyfrakcyjnych wskazują, że podczas odkształcenia plastycznego na zimno w stopie zachodzi mechaniczne bliźniakowanie i przemiana martenzytyczna. Występują zależności krystalograficzne pomiędzy austenitem (faza γ) i martenzytem (faza ε i faza α’), które opisują zależności: Shoji-Nishiyama {00.2}ε || {111}γ, <11.0>ε || <110>γ i Kurdjumowa-Sachsa {111}γ || {110}α, <110>γ || <111>α.
