Journal ArticleDOI
Fabrication process of carbon nanotube/light metal matrix composites by squeeze casting
Uozumi Hisao,Kenta Kobayashi,Kota Nakanishi,Tadashi Matsunaga,Kenji Shinozaki,Hiroki Sakamoto,Takayuki Tsukada,Chitoshi Masuda,Makoto Yoshida +8 more
TL;DR: In this article, the authors measured the wettability of the basal plane of graphite by molten aluminum or magnesium was measured using the sessile drop method, and trial fabrication of multi-walled carbon nanotubes (MWCNTs) reinforced aluminum and magnesium alloy composites was carried out by squeeze casting.
Journal ArticleDOI
The homogeneous dispersion of surfactantless, slightly disordered, crystalline, multiwalled carbon nanotubes in α-alumina ceramics for structural reinforcement
TL;DR: In this article, carbon nanotubes (CNTs) were successfully prepared and then homogeneously and individually incorporated in an α-alumina ceramic by a recently established powder technology to investigate their load-carrying and reinforcing capabilities.
Journal ArticleDOI
Fabrication and Thermal Properties of Carbon Nanotube/Nickel Composite by Spark Plasma Sintering Method
Shunsuke Yamanaka,Ryohei Gonda,Akira Kawasaki,Hiroki Sakamoto,Yutaka Mekuchi,Masaki Kuno,Takayuki Tsukada +6 more
TL;DR: In this paper, a nickel-matrix composite with multiwall carbon nanotube (MWNT) was prepared by slurry mixing process using ethanol as a solvent, using spark plasma sintering (SPS).
Journal ArticleDOI

Laser processing arrangement
TL;DR: In this article, a laser processing arrangement includes a temperature sensor associated with a temperature detecting means, which is connected to a control unit which controls moving means connected to movable axes of a processing surface in order to move the work piece relative the laser beam.
