Wettability of SnCuNi-xEu solders and mechanical properties of solder joints张亮1,2,田磊3,郭永环1,孙磊1,闵勇11. School of Mechanical and Electrical Engineering, Jiangsu Normal University2. Department... enhance the properties of solder and solder joints, with the increase of Eu content, tendency of first increase and then decrease could be found in the wetting time, wetting force and the mechanical......
Diffusion in FSW Joints by Inserting the Metallic FoilsS.Gholami Shiri1,A.Sarani2,S.R.Elmi Hosseini2,G.Roudini21. School of Materials Science and Engineering,Department of Engineering,Shiraz... to study diffusion phenomenon in friction stir welding(FSW) joints and its influence on the tensile strength of joints.To study diffusion in stir zone,various metallic foils were inserted between two pure......
Fatigue behaviour of welded joints assembled by longitudinal corrugated platesWANG Zhi-yu(王志宇)1, 2, WANG Qing-yuan(王清远)1, 2, Liu Yong-jie(刘永杰)1, 2, Sun Mei(孙美)3(1. Department of Civil Engineering... behaviour of welded details in such structures becomes an important issue for the design. The typical welded details were represented as welded joints assembled by longitudinal corrugated plates. All......
different types of joints,(Ti matrix)/(AlN particles),(Ti particles)/(AIN plate),and (Ti plate)/(AlN plate),were analyzed theoretically under the reported experimental conditions.Different phase formation sequences for the three kinds of Ti/AlN joints were obtained.It proved that the different phase sequences of both the phase formation sequences and the apparent spatial phase sequences......
New criterion for rock joints based on three-dimensional roughness parametersTANG Zhi-cheng(唐志成)1, 2, LIU Quan-sheng(刘泉声)1, HUANG Ji-hui(黄继辉)2(1. School of Civil Architectural Engineering, Wuhan University, Wuhan 430072, China;2. Department of Geotechnical Engineering, Tongji University, Shanghai 200092, China)Abstract:The shear behavior of rock joints is important in solving practical problems......
with an energy dispersive spectrometer (EDS) and an electron probe X-ray microanalyzer (EPMA). The structure of joint interface was identified by XRD (JDX-3530M). Meanwhile, the fracture paths of the joints were comprehensively studied. The results show that processing parameters, especially the brazing temperature, have a significant effect on the microstructure and mechanical properties of joints......

when joining thin sheets. Three tools, with several convex-vortex pins were innovatively designed to improve the diffusion bonding effect of the lap interface. Results showed that sound joints, excellently bonded at the lap interface and without hook, were obtained. The lap interfaces on the joints welded using the T-tool and F-tool almost remained intact, thereby indicating that they were formed......
. The relationship between pin length and mechanical properties of lap joints was studied. The results showed that the peak temperatures of all joints exceeded A c3, and martensite phases with similar... for the hardness reduction in heat-affected zone. The mechanical properties of the lap joints were determined by loading mode, features of lap interface and the joint defects. When the stir pin was inserted......
of Sn3.0Ag0.5Cu solder.The melting behavior of the solder alloys was determined by differential scanning calorimetry.The interfacial microstructure and phase composition of solder/Cu joints were......
