fillers on interfacial microstructure and shear strength were studied. And the optimum joining parameters were given. The brazed joints were qualitatively and quantitatively analyzed by means of EPMA, SEM and XRD. The results show that using brazing filler NiCrSiB, TiAl3, AlNi2Ti and Ni[s,s] are formed at the interface of joint, and the formation of Ti3Al and AlNi2Ti decreases the shear strength. Using......

supercooling. The significantly increased shear strength of the transient current bonding and the change in the fracture mechanism were due to the uniformly distributed Ag-GNSs and the microstructural changes. Key words: transient current bonding; Ag-GNS; Cu6Sn5; shear strength 1 Introduction Sn-Ag-Cu (SAC) solder has been extensively applied in the electronic industry to replace the traditional Pb-Sn......
fitting formula. The results show that the shear strength of concrete pile-clay interface accords with Mohr-Coulomb failure criterion, and the failure mode is shear slip failure of interface... normal stress. Although the shear strength of interface follows the power function relationship with the roughness, the effect of roughness on shear strength decreases with the increase of normal stress......
. Relationship curves between shear stress and shear deformation for clay stone with different normal stresses and water contents were obtained. The shear strength parameters were calculated using least... stress, while they decrease with the increase of water content. The decrease range of cohesion is larger than that of friction angle, and the decrease range of shear strength for siltstone is larger......

Municipal Engineering Design & Research Institute, Tianjin 300051, China) Abstract: A series of large direct shear tests were carried out to investigate the effect of roughness on residual shear strength......
with the results in natural state, the decline extent of shear parameters was analyzed quantitatively. The test results show that the shear strength of rock mass is relevant to not only positive stress but also to water content of the rock mass. The shear strength of rock mass in saturation decreases by 11.17% averagely compared with that in the natural state, and the decreased extents of cohesive......
