302 ACサーボプレスを用いたマグネシウム合金の鍛造基礎特性(塑性加工) [in Japanese] 302 Forgeability of Magnesium alloy using AC Servo-Controlled Press [in Japanese]
Access this Article
Forgeability of magnesium alloy AZ31B (Mg-3%Al-1%Zn) is investigated by upsettability test on AC servo-controlled press at elevated temperature. The slide speed and motion of AC servo-controlled press are controlled by servo motor. When the AZ31B billet is compressed with decelerating motion of the punch at the temperature of 200℃, the ductility is improved and it is possible to compress the billet without cracking up to the reduction in height of 70%.
