| Abstract: | Ti was added into carbon structural steel (35# steel) base components. The end quenching test and microstructure observation indicated that the hardenability of steel was greatly improved after adding Ti. It increased Ti about 5HRC at J3 point, 10HRC at J5 point and 4HRC at J7 point, respectively. The experimental results showed that Ti had a significant influence on the improvement of hardenability of carbon steel. |
