in the microstructure and joint performance of Mg-Cu joints. However, diffusion bonding can be used to join these alloys without much difficulty. This work analyses the effect of parameters on diffusion layer... relationships were developed to predict diffusion layer thickness, hardness and strength using response surface methodology. It is found that bonding temperature has predominant effect on bond characteristics......
of thin Ta-Si-N diffusion barriers for Cu metallization [J]. Thin Solid Films, 2006, 500(1/2): 259-268. [3] KHIN MAUNG LATT, LEE Y K, LI S, OSIPOWICZ T, SENG H L. The impact of layer thickness of IMP...

Effect of Rare Earths on Diffusion Coefficient and Transfer Coefficient of Carbon during Carburizing 刘志儒1,阎牧夫1 (1.School of Materials Science and Engineering, Harbin Institute of Technology,) Abstract:The diffusion coefficient of carbon in surface layer of steel-20 rare earth carburized at 880 ℃ and 900 ℃ for 8 h was calculated by substituting the measured layer depths into the diffusion......
in Teflon-lined autoclave at 120 °C after pre-depositing by dip-coating at room temperature. No visible cracks, pinholes or other defects were observed on the membrane layer. The gas separation studies... an increase with the increase of temperature. This different behaviour of CO2 was reported by ZHAO et al [43]. The permeance of gas depends on the relative values of activation energy for diffusion......
reaction layer. In nature, interfacial reaction mechanism and product formation are affected by the Si diffusion behavior. The Si diffusion behavior will be analyzed from the view of Si chemical potential... line due to Si and Al diffusion. The solid-state phase changed reaction layer with Ti3Al and precipitation Ti5Si3 is formed. In zone Ⅱ, eutectic reaction appears in melting Ti alloy near fusion line......

ethylene-air diffusion flames was presented. A numerical simulation was conducted by using a relatively detailed gas-phase chemistry and complex thermal and transport properties coupled with a semi... method were combined to explore the flame structure and soot volume fraction. A numerical study of soot formation was conducted in an axisymmetric laminar diffusion ethylene flame using detailed gas......
. These results suggest that the α-terpineol molecule layer could better block the diffusion of gas through the liquid film than DF200 and MIBC. The simulation results indicate that the foam stability... how the layer of frother molecules absorbs at the gas-liquid interface, the Forcite module is used in this work. The smart module is selected as the algorithm and the convergence criteria is set to 1......
