Bonding interface zone of Mg-Gd-Y/Mg-Zn-Gd laminated composite fabricated by equal channel angular extrusion WU Di(吴 迪)1, 2, CHEN Rong-shi(陈荣石)1, HAN En-hou(韩恩厚)1 1. State Key Laboratory... investigated on the bonding interface zone of GW55/ZG21 laminated composites. The bonding interface zone of GW55/ZG21 laminated composites comprises a lot of Mg3(Y, Gd)2Zn3 particles along the bonding interface......
at interface of steel-backed Al-graphite semi-solid bonding plate ZHANG Peng(张 鹏)1, DU Yun-hui(杜云慧)1, LIU Han-wu(刘汉武)1, ZHANG Jun(张 君)1, ZENG Da-ben(曾大本)2, BA Li-min(巴立民)3 (1. Department..., Anshan 114014, China) Abstract: The ratio of Fe-Al compound at the bonding interface of solid steel plate to Al-7graphite slurry was used to characterize the interfacial structure of steel......
Effect of ultrasonic power on wedge bonding strength and interface microstructure WANG Fu-liang(王福亮), LI Jun-hui(李军辉), HAN Lei(韩 雷), ZHONG Jue(钟 掘) School of Mechanical and Electrical...; 3) only when ultrasonic power is between 1.0 W and 1.6 W, can stable and high yield bonding be reached. Finally, the microstructure of bonding interface was observed, and a ring-shaped bond pattern......

features of the bonding interface, such as elastic modulus, tensile strength of gold ball and Ag substrate, which results in different bonding strengths. Moreover, the temperature change also... and amplified by the tapered horn. The wave was converted to flexural vibration in the bonding capillary and transmitted to the bond interface during a bonding process. So, under the environment......
Study on the Interface Bonding and Bending Fatigue Properties of Aluminum Alloy Foam Sandwich () 摘要:Foam materials have many attractive properties because of their low-weight and cell structure... end-use product. Aluminum alloy foam sandwich is obtained in this experiment. The experimental results showed that the process of rolling interface belongs to mechanical bonding, whose mechanism is film......
Trans. Nonferrous Met. Soc. China 22(2012) s645-s649 Effect of bonding interface on delamination behavior of drawn Cu/Al bar clad material Sangmok LEE1, Min-Geun LEE2, Sang-Pill LEE3, Geun-Ahn LEE1... material was fabricated by a drawing process and a subsequent heat treatment. During these processes, intermetallic compounds have been formed at the interface of Cu/Al and have affected its bonding......
in bonding interfaces. And there is no obvious element diffusion on the both sides of bonding interface. Key words: Nb/304L; explosive cladding; interface bonding interface is the highest[13]. Fig.5 Elements distribution lines between interfaces: ......
Interface structure of ultrasonic wedge bonding joints of Ni/Al LI Jun-hui(李军辉), HAN Lei(韩 雷), ZHONG Jue(钟 掘) (School of Mechanical-Electronical Engineering, Central South University...]. In this paper, characteristics at bonding micro-interface were observed by scanning electron microscopy and EDS-test, features of power of PZT transducer were analyzed by the driving electric signal measured......
: The lift-off characteristics at the interface of thermosonic bond were observed by using scanning electron microscope (JSM-6360LV). The vertical section of bonding point was produced by punching, grinding... interface but in basis material, and the bonded strength at interface is enhanced by diffused atom from the other side. Key words: thermosonic bond; atomic diffusion; dimples, bonding strength ......
