Autor: Kunio Takada, Tetsuya Ashino, Kenji Abiko, Yukitoshi Morimoto, Toshiko Itagaki, Kazuaki Wagatsuma

Publikováno v: Materials Transactions. 43(2):105-110

When trace elements in an ultra high-purity iron were determined, an analytical blank on a chemical analysis interfered with the determination of them. Similarly, the existence of major component in a sample interfered with the determination of trace

Purification of Ti–Al Alloys by Induction-Heating Floating-Zone Melting and Cold-Crucible Melting in Ultra-High Vacuum

Autor: Tadahito Nakajima, Kenji Abiko, Seiichi Takaki, Yukitoshi Morimoto

Publikováno v: Materials Transactions, JIM. 41:22-27

The effect of ultra-high vacuum melting on the purification of Ti-Al alloys, especially on reducing gaseous impurities, is investigated using new floating-zone melting furnace and cold-crucible melting furnace in which ultra-high vacuum of 10 -7 Pa i
