Trans. Nonferrous Met. Soc. China 25(2015) 3363-3369 Free dendritic growth model incorporating interfacial nonisosolutal nature due to normal velocity variation Shu LI1,2, Zhi-hui GU1, Da-yong LI2...; accepted 4 March 2015 Abstract: Considering both the effects of the interfacial normal velocity dependence of solute segregation and the local nonequilibrium solute diffusion, an extended free......
Interfacial characteristics and dynamic mechanical properties of Wf/Zr-based metallic glass matrix composites MA Wei-feng(马卫锋), KOU Hong-chao(寇宏超), CHEN Chun-sheng(陈春生), LI Jin-shan(李金山), HU Rui... using a Hopkinson bar. The relationship between the interfacial characteristics and the dynamic compressive behavior was investigated. The results indicate that the interface characteristics......
, Northeastern University, Shenyang 110004, China) Abstract: Through scanning electron microscopy and metallograph microscopy, the restraining mechanism of steel aluminum rolling bonding interfacial high temperature compound building was investigated. The results show that, by adding alloying element Si to aluminium and nitrogen to steel, the interfacial compound building is obviously restrained. Besides......
a significant effect on the formation of interfacial intermetallic compounds. To analyze the Si diffusion behavior, a model for the prediction of the chemical potential for ternary alloy was established... dissolution and melting mode, which presents a good agreement with the experimental data. Further, formation mechanism of the interfacial intermetllic compound was clarified. Key words: laser welding......

Symmetric redox......
INVESTIGATIONS ON THE INTERFACIAL ZONE BETWEEN AGGREGATE AND PORTLAND SLAG CEMENT PASTE余其俊,胡明德,钱进夫,王旭,陶从喜摘 要:<正>The composition and structure of the interfacial zone be-tween aggregate and portland slag cement paste as well as the orienta-tion coefficient of portlandite(ICH) have been studied by means ofXRD and SEM. The results show that the main......
rate of interfacial crud increases with increasing cycle times. The interfacial crud contains jarosite, silica and bacterial. And the organic phase structure changes, IR results show...+ to form a complexes in the extraction process. The micro-solid particles, cumulative leaching bacteria and organic phase with changed structure lead to the formation of interfacial crud in microbial......
