“…alloys (HIRSCH et al, 1988;DONADILLE et al, 1989;SALEH et al, 2011). In previous work (SOUZA et al, 2015) it was reported that strong mechanical twinning formed in the 2Al steel at higher strain (~0.7). This accompanied the formation of G, and B texture components (Fig.…”

“…2) at ε=0.69, where shear banding was activated (Fig. 5) (SOUZA et al, 2015). In summary, the 8Al steel at reduction ranged in 10%-40% has Cu, G, and B components with f(g)=6 and at 50% G component increases to f(g)=8, while the 2Al steel at reduction ranged in 10%-40% has G and B components with about f(g)=6 and G component with f(g)=9 and B with f(g)=8 at 50%.…”

“…The Fe-30.5Mn-2.1Al-1.2C (wt.%) (2Al) and alloys have medium and high Stacking Fault Energy, SFE, respectively (SOUZA et al, 2015). The crystallographic texture evolution in deformed TWIP steels of the Fe-Mn-C system has been largely studied (BOUAZIZ et al, 2011;DE COOMAN et al, 2011;GAZDER et al, 2011;BRACKE et al, 2009).…”

Crystallographic textures of the austenitic low-density Fe-30.5Mn-8.0Al-1.2C (8Al) and Fe-30.5Mn-2.1Al-1.2C (2Al) (wt.%) steels were examined during cold rolling by means of electron backscatter diffraction (EBSD) and electron channeling contrast imaging (ECCI). Random oriented grains orient towards Goss-and brass-components along the α-fiber as the strain increased, with activation of slip, mechanical twinning, and shear banding, for both steels. S-and copper-orientations were also observed in the 8Al steel at 50% reduction. The route of Cu-CuT-Gossbrass texture evolution was found in the 2Al alloy. Cu, Goss, and brass textures occur as a dominant texture in the deformed 8Al alloy. Copper-type texture accompanied with slip at low reduction (20%), as well as Cu-type shear bands, and shear banding inside Goss-oriented grains at higher reduction (50%), were observed in the 8Al steel. It is suggested that this copper-type rolling texture may be attributed to the Al addition, which contributes to its low twinning activity compared to that in the 2Al alloy. Cu-CuT-brass f.c.c. rolling texture transition to form the Brass-type texture was observed at higher reduction in the 2Al alloy with strong similarity to that found in other Fe-Mn-C system TWIP steels.
