Grain Boundary Design and Control for High Temperature Materials. (1998)
Recent experimental work has been reviewed concerning the effects of grain boundary structure on grain boundary sliding and migration, and other boundary phenomena involved in high temperature...
Effects of Cr on the Mechanical Properties and Phase Formation of Mo2NiB2 Boride Base Cermet. (1998)
Komai, Masao, Yamasaki, Yuji, Takagi, Ken-ichi, Watanabe, Tadao
In this study, ni-6wt%b-58.6wt%mo-xwt%cr cermets with five levels of cr content from 0 to 20 wt% were prepared to investigate the cr effects on mechanical properties and phase formation of mo2nib2...
Effects of Cr on the Mechanical Properties and Phase Formation of Mo2NiB2 Boride Base Cermet. (1998)
Komai, Masao, Yamasaki, Yuji, Takagi, Ken-ichi, Watanabe, Tadao
A new type of Mo2NiB2 complex boride base cermet consists of a Mo2NiB2 type ternary boride as the hard phase and nickel base binder alloyed with Cr, Mo and other elements; both of which are formed by...
Fracture Toughness Measurements of Ceramics by V Notch Technique. (1998)
Awaji, Hideo, Watanabe, Tadao, Sakaida, Yoshihisa, Nakagawa, Heisaburo
It has been made clear that the values of the fracture toughness of structural ceramics can be accurately obtained by applying the highly skilled technique of cutting a V-shaped notch sharply into...
Compressive Testing of Ceramics. (1998)
Awaji, Hideo, Watanabe, Tadao, Nagano, Yasuo
Research has been conducted towards the development of a compressive test method more suitable than present procedures for use on advanced ceramics with extremely high compressive strength. A...
The importance of grain boundary character distribution (GBCD) to materials development by grain boundary design is briefly discussed. Particular attention has been paid to the relationship between...
Above-Ground Biomass and its Vertical Distribution of a Young Quercus serrata Plantation (1986)
WATANABE, Tadao, YAGI, Kitokuroo
Above-ground biomass and its vertical distribution in a 4-year-old closed stand of Quercus serrata planted in the Tokyo University Forest at Tanashi near Tokyo were studied in November, 1978. The...
OHYAMA, Kunio, KANEKO, Ichiro, YAMAKAWA, Toshio, WATANABE, Tadao
Two enzymatically active forms of valyl-tRNA synthetase [EC 6.1.1.9] were found in the cells of Bacillus subtilis. The aminoacylation activities of the two forms were altered during the sporulation...
Hatano, Shoji, Sadakane, Haruo, Tutumi, Masakazu, Watanabe, Tadao
Chlorella ellipsoidea cells at an intermediate stage in the ripening phase of the cell cycle were brought into contact with inhibitors of RNA and protein synthesis, and surfactants during or after...
Hatano, Shoji, Sadakane, Haruo, Tutumi, Masakazu, Watanabe, Tadao
Cells of Chlorella ellipsoidea Gerneck (IAM C-27) were synchronously grown under a 28-hr light-14-hr dark regime at 25°C. The algal cells at different stages during the cell cycle were hardened at...
