- •
Evolution of ultrafine grained interstitial free steel by multiaxial forging (MAF).
- •
Experimental parameters were designed through dilatometric study using Gleeble-3800 simulator.
- •
The specimen forged at pure ferritic region shows best combination of YS and ductility.
- •
EBSD study confirms the formation ultrafine grains with high angle of misorientation.
- •
Nanosize Ti–Nb carbides and dislocation strengthening play vital roles to produce ultrafine grained steel through MAF.
