Grain refinement of a commercial 0.15%C steel by equal-channel angular pressing

The commercial 0.15% C steel was subject to ECA pressing for the increase of strength through grain refinement. The UTS has increased by approx70% from 450-750 MPa after a single pass through the die. This result exhibits a potential to produce a low carbon steel of high-strength without investing n...

Zusammenfassung:	The commercial 0.15% C steel was subject to ECA pressing for the increase of strength through grain refinement. The UTS has increased by approx70% from 450-750 MPa after a single pass through the die. This result exhibits a potential to produce a low carbon steel of high-strength without investing new composition or complicated heat-treatment procedures.
