| Abstract: | Regularity of Variation of grain size and precipitated phases under different double heating conditions as well as relevant mechanical properties of forged specimens and parts made from medium carbon non-quenched -tempered steel F35MnVN were introduced. The test showed that the double heating is an important way to improve on toughness of the non-quenched-tempered steel and for the steel to obtain excellent strenth and toughness. The application of such a technology to automobile parts was also briefly described. |
