スポンサーリンク
概要
- 論文の詳細を見る
Central cracking of a brittle metal during cold-extrusion and its prevention by applying a hydrostatic back pressure are studied in relation to the fracture characteristics of the material. The fracture strain of magnesium is obtained experimentally as a function of hydrostatic component of stress. The critical back pressure to prevent cracking is obtained experimentally. The critical back pressure shows the maximum value at a certain extrusion ratio, which is dependent on die angle.
