【Abstract】 TTT-diagrams of intermediate temperature in some low carbon alloy steelsusually consist of three C-curves and the structures corresponding to theseC-curves are granular one produced in higher C-curve,upper bainite pro-duced in intermediate C-curve or lower bainite produced in lower C-curve.The other diagrams in some intermediate carbon alloy steels usually consistof two C-curves and the structures corresponding to these curves are upperbainite produced in higher C-curve or lower bainite produced in lower C-curve.更多还原
