Microstructure characteristics in high carbon steel rod after warm cross-wedge rolling

An ultrafine ( α + θ) structure is successfully produced through warm cross-wedge rolling at the outer layer of high carbon steel rod where equiaxed α grains and fully spheroidized θ particles are in submicron scale. In the central region of the rod, original lamellar θ is fragmented but the spheroi...

Zusammenfassung:	An ultrafine ( α + θ) structure is successfully produced through warm cross-wedge rolling at the outer layer of high carbon steel rod where equiaxed α grains and fully spheroidized θ particles are in submicron scale. In the central region of the rod, original lamellar θ is fragmented but the spheroidization is not complete.
