Autor: Takashi SUMIGAWA, Emi KAWAI, Tomoya MARUMO, Hisashi TANIE, Takayuki KITAMURA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 81, Iss 831, Pp 15-00446-15-00446 (2015)

The purpose of this study is to investigate the dominant factor on the fracture strength of thin film comprising of copper (Cu) helical nano-elements, which are grown by the glancing angle deposition technique. By changing the deposition angle in the

Inductive Determination of Rate-Reaction Equation Parameters for Dislocation Structure Formation Using Artificial Neural Network

Autor: Yoshitaka Umeno, Emi Kawai, Atsushi Kubo, Hiroyuki Shima, Takashi Sumigawa

Publikováno v: Materials; Volume 16; Issue 5; Pages: 2108

The reaction–diffusion equation approach, which solves differential equations of the development of density distributions of mobile and immobile dislocations under mutual interactions, is a method widely used to model the dislocation structure form

Controlling the Nanostructure and Thermal Properties of Double-Perovskite Rare-Earth Tantalates by Elemental Doping

Autor: Craig A. J. Fisher, Daisaku Yokoe, Naoki Kawashima, Takafumi Ogawa, Emi Kawai, Satoshi Kitaoka, Takeharu Kato, Tsuneaki Matsudaira

Publikováno v: SSRN Electronic Journal.

Controlling the complex nanostructures that often form in cation-deficient oxides may provide an effective way to tailor their thermophysical properties, but this remains a challenging task. We report a study of un-doped and Hf-doped YTa3O9 with a Y-

Spontaneously formed nanostructures in double perovskite rare-earth tantalates for thermal barrier coatings

Autor: Naoki Kawashima, Tsuneaki Matsudaira, Daisaku Yokoe, Craig A. J. Fisher, Takeharu Kato, Satoshi Kitaoka, Habu Yoichiro, Takafumi Ogawa, Emi Kawai

Publikováno v: Acta Materialia. 216:117152

The identification of low thermal-conductivity materials that are stable up to high temperatures has been a longstanding challenge for high-temperature thermal management systems such as thermal barrier coatings (TBCs). Although phonon scattering in

Delamination crack initiation from copper/silicon nitride interface edge with nanoscale singular stress field

Autor: Takashi Sumigawa, Kazunori Sanada, Takayuki Kitamura, Emi Kawai

Publikováno v: Engineering Fracture Mechanics. 120:60-66

In order to investigate delamination crack initiation from an interfacial edge in nanoscale component with the singular stress field, we conduct mechanical experiments using four kinds of cantilever specimens with the nanoscale singular stress field
