- Abstract
This study investigated a forming feasibility for hot forging by using lower strength material as a die. In this paper, the AISI1050 steel was employed not only for heating the billet, but also to forming the billet. In this proposed method, the die can be used as the electrode to raise the temperature of the billet directly by resistance heating. The higher the temperature of the billet; the lower the flow stress of the billet. Then, the billet is easier to press into the cavity of the die. In addition, the die itself could not be heated by electrification and the temperature rise of the die occurred because of the heat transfer from the heated billet. Therefore, the die can be carried out on the hot forging process to achieve the purpose of forming. The result of the experiment shows that the billet could be heated quickly to 1000°C in about 5 seconds, and a spur gear was successfully formed. With the proposed method, it was simple enough to hot forge the high-alloy metals with a poor workability. [ABSTRACT FROM AUTHOR]
