Effect of temperature rise on microstructural evolution during high-pressure torsion

Dynamic recrystallization occurs at room temperature during high-pressure torsion (HPT) leading to the formation of ultrafine grains with high angles of misorientation. There are questions concerning whether dynamic recrystallization occurs due to the temperature rise during severe plastic deformati...
