Effect of Tempering Temperature on Tensile Behavior of Low Carbon Steel
저탄소강의 템퍼링 온도가 인장거동에 미치는 영향
Abstract
The disappearance of continuous yielding and the formation of an extended region in engineering stress-strain curves at tempering temperatures of 673-873K is closely related to the reduction of mobile dislocations during tempering and dynamic recovery during tensile deformation. In addition, the occurrence of discontinuous yielding at tempering temperature above 923K would be attributed to the formation of new strain-free polygonal ferrite grain.
