Development of adhesion preventing method during deep drawing of TP340 titanium sheets
Autor: Taku Iwaoka, Isao Nakamura, Yusuke Okude
Publikováno v: Advances in Materials and Processing Technologies. 8:85-95
Generally, the adhesion of titanium alloys easily occurs between die and blank during press forming because the sliding and contact surface of die and blank with high surface pressure. In the case ...

Development of Warm Press Forming Process Method of Ti–6Al–4 V Alloy Sheet
Autor: Taku Iwaoka, Isao Nakamura, Yusuke Okude, Takashi Katagiri
Publikováno v: Forming the Future ISBN: 9783030753801
Because of the low ductility of Ti–6Al–4V alloy at the temperatures between room temperature and 600 °C, fracture easily occurs during press forming. Hence, a method of press forming of Ti–6Al–4V alloy sheets at 300 °C was developed. In thi

Development of Adhesion Preventing Method During Deep Drawing of Titanium Alloy Sheets
Autor: Yusuke Okude, Isao Nakamura, Taku Iwaoka
Publikováno v: Forming the Future ISBN: 9783030753801
It is necessary to prevent the surface oxide film peeling caused by sliding between workpiece and die material with high surface pressure for reducing punch load and preventing fracture. Hence, we have focused on the method to prevent the titanium su

Effect of Sn, Zn and Bi Addition on Corrosion Characteristics of Magnesium Alloys Sintered by Spark Plasma Sintering
Autor: Koichi Sato, Taku Iwaoka, Satoshi Sunada, Syogo Takeuchi, Yoshitaka Matsui, Masahiko Hatakeyama
Publikováno v: Materials Science Forum. 941:1760-1765
Sintered magnesium alloys, which were fabricated by Spark Plasma Sintering (SPS) method, were examined to study corrosion characteristics by electrochemical method, XRD and EPMA. The binary mixtures alloys of a low-melting-point metal powder (Sn, Bi,

Forming limit diagram with anisotropy considering of Ti-6Al-4V sheets and prediction of ductile fracture by experiment and FEA
Autor: Yasuyoshi Saito, Taku Iwaoka, Yusuke Okude
Publikováno v: Procedia Manufacturing. 15:931-939
Ti-6Al-4V titanium alloy sheets were focused on to clarify the forming limit curve. At first, finite element analysis (FEA) was utilized to calculate the suitable dimension of the sheet to the extent heretofore provided in ISO 12004 and to determine
