前後方缶の組合せ押出し鍛造における押出し長さおよび荷重に及ぼすビレット高さ/直径比の影響
Combined extrusion forging is effective in load reduction and process simplification. However, combined forging is not used widely. The reason for this seems to be the load and metal flow being difficult to assume. Many research studies have been conducted to solve this problem. Although it is considered that extrusion load and metal flow are affected by the shape ratio of a billet (ho/do), research on this subject is insufficient. In this study, the effects of the shape ratio of a billet on
