Lowering the forging finish temperature causes the final grain size to become smaller, and improves the impact toughness.<\/p>\n<p>As shown in Fig. 10&nbsp;above, the grain size of steels rolled at a lower temperature is much smaller. Vanadium alloying increases the effects over those of rolling at a conventional temperature without vanadium, and contributes to the improvement of toughness.<\/p>\n<p>However, in DHT steel processing, a decrease of hot forming temperature leads to deterioration in die life and in the accuracy of forged parts. Investigation of other methods was therefore encouraged.<\/p>\n<p><i>For more information, click on the link below (subscription required).
