Description

   Die quenching process is aiming at manufacturing a high-strength steel parts with good accuracy by combining hot forming with rapid cooling due to the heat conduction from the hot sheet to the dies. This process is quite promising one, however, technological problems such as lower productivity resulting from the temperature rise should be solved for the greater development of this process and wider area of application. As we need precise information about the die quenching process, such as the transient change in temperature during forming and hardness distribution of the formed and quenched product, we carried out the die quenching experiment by a high precision material testing machine and water-cooling dies.
