Autor: Atsunori Kamegawa, Jun Nakahigashi, Miho Yamauchi, Asaya Fujita, Masuo Okada
Publikováno v: Journal of Alloys and Compounds. 580:S401-S405
Useful functions of hydrogen in materials are studied. (a) Simultaneous improvements of electrical conductivity and mechanical strength for Cu–3mass%Ti hydrogenated alloy were achieved. The hydrogenation reaction proceeds within the range of spinod

New function of hydrogen in materials
Autor: Miho Yamauchi, Atsunori Kamegawa, Akira Yamaguchi, Masuo Okada, Asaya Fujita, Jun Nakahigashi
Publikováno v: Materials Science and Engineering: B. 173:253-259
Useful functions of hydrogen found recently in materials are reviewed with newly obtained results. By hydrogen absorption–desorption heat-treatment, grain size of Cu–Ti alloys are refined to several 10 nm. Simultaneous improvements of electrical

Publikováno v: Journal of the Japan Institute of Metals. 70:204-211
Hydrogen treatment is one of the few possible methods for producing a fine-grain size of 0.3 to 0.5 μm in α+β Ti-6Al-4V alloys. The process of hydrogen treatment involves hydrogen absorption, quenching, hot rolling and hydrogen desorption. However
