Journal ArticleDOI
Preparation and optical properties of Ga1−xInxN thin films
TL;DR: In this article, the authors used the electron beam plasma technique to synthesize solid solutions of Ga1−xInxN and found that the solid solution of GaN can be synthesized over the entire composition region.
Journal ArticleDOI
Fundamental absorption edge in GaN, InN and their alloys
TL;DR: In this article, optical measurements were performed near the fundamental absorption edge for thin polycrystalline films with the entire region of composition in the GaNInN quasi-binary system.
Journal ArticleDOI
Phase diagram of the Nd-Fe-B ternary system
Yutaka Matsuura,Satoshi Hirosawa,Hitoshi Yamamoto,Setsuo Fujimura,Masato Sagawa,Kozo Osamura +5 more
TL;DR: An experimental study of the liquidus projection in a phase diagram of the Nd-Fe-B ternary system has been carried out in this article, where two monovariant curves, L\rightleftharpoonsFe+Fe2B and L\ rightlefthsarpoons Fe2B+T2, join and form the transition reaction.
Journal ArticleDOI
Enhancement of critical current density of YBCO films by introduction of artificial pinning centers due to the distributed nano-scaled Y2O3 islands on substrates
Kaname Matsumoto,T. Horide,Kozo Osamura,Masashi Mukaida,Yutaka Yoshida,Ataru Ichinose,Shigeru Horii +6 more
TL;DR: In this paper, the authors introduced high-density extended crystalline defects, which result in artificial pinning centers of the quantized vortices, into c-axis oriented YBa 2 Cu 3 O 7− x (YBCO) films.
Journal ArticleDOI
Precipitation Hardening in Fe-Cu Binary and Quaternary Alloys
Kozo Osamura,Hiroshi Okuda,Shojiro Ochiai,Minoru Takashima,Kazuo Asano,Michihiro Furusaka,Koji Kishida,Fumio Kurosawa +7 more
TL;DR: The behavior of precipitation hardening in two types of Fe-Cu alloys has been investigated by means of mechanical tests as well as small angle neutron scattering measurements as discussed by the authors, and it was found that the loss of coherency with the matrix greatly lowers the strengthening effect whereby the structure of precipitates changes from bcc to fcc during aging.
