J. Cent. South Univ. Technol. (2008) 15: 89-94 DOI: 10.1007/s11771-008-0018-7 Formation mechanism of breccia pipe type in Yixingzhai gold deposit SHAO Yong-jun(邵拥军), ZHANG Yi-zhou... mineral composition, structure and construction, typical mineralization alteration phenomenon on field and microscopic anatomy in breccia pipes. And the ore-controlling mechanism and the formation......
Microstructure and brazing mechanism of porous Si3N4/Invar joint brazed with Ag-Cu-Ti/Cu/Ag-Cu multi-layered fillerJ.Zhang,J.Y.Liu,T.P.WangSchool of Materials Science and Engineering, Harbin Institute of Technology摘 要:Porous Si3N4 was brazed to Invar alloy in this study, and Ag-Cu-Ti/Cu/Ag-Cu multi-layered filler was designed to inhibit the formation......
that the surface oxide layer on TiAl plays a very important role in the formation process of the joint. A ‘bridge’ effect is observed because of the presence of the oxide layer on the surface of TiAl... pressure, bonding temperature, holding time and stacking sequence of the insert foils on the joint formation process were proposed. Key words: TiAl; Ti6242 transient liquid phase bonding......
composite coatings was developed. Key words: carbon-carbon composite; TaC; SiC; structure; formation mechanism  ... is then to investigate the design methodology, preparation and structural morphology of coatings of TaC (as reference) and TaC/SiC composite. The formation mechanism and optimal preparation......
: Rock joint shape characteristics, waviness and unevenness play essential but distinct roles in shear mechanism of rock joints. This study presents a novel method to generate virtual rock joint... the entire rock joint surfaces. The working theory of this method is to measure the spatial distance based on the triangulation mechanism. In this system, the laser dot, the camera and the laser......
