Numerical simulation of copper based filler metal droplets spreading under arc brazing YU Zhi-shui(于治水)1, LI Rui-feng(李瑞峰)2, QI Kai(祁 凯)2, ZHOU Fang-ming(周方明)2 (1. College of Materials...) Abstract: The spreading behavior of copper filler metal droplets under arc brazing was studied by numerical simulation method using Surface Evolver software. The mathematical model in which arc......
Influence of laser energy input mode on joint interface characteristics in laser brazing with Cu-base filler metal LI Li-qun(李俐群), FENG Xiao-song(封小松), CHEN Yan-bin(陈彦宾) State Key Laboratory... spot, the joint interface layer is also formed. The layer thickness is larger than that of dual-beam brazing and the layer shape is flat so that intermetallic compounds trend to grow into cellular......

Laboratory for Terrain-machine Bionics Engineering, Ministry of Education, Jilin University, Changchun 130025, China) Abstract: A new-type BCu80Ni5SnTi filler metal suitable for brazing cubic......
入Zn-Al中时,银元素与钎料中的锌和铝都能形成固溶体,从而可以提高钎料熔点. 表5 Ag-Cu-Zn钎料的熔化温度 Table 5 Melting temperature of Ag-Cu-Zn(-Sn) brazing filler metals 2.2 硬钎料的显微组织 Ag-Cu-Zn钎料中有α-(Cu-Zn),α-(Ag-Zn),β,γ,δ,ε,η等... brazing filler metals 图10 Cu-P-xAg的显微组织 Fig. 10 Microstructures of Cu-P-xAg brazing filler metals Zn-Al钎料组织如图11所示.银主要以固溶体形式存在,钎料组织是锌原子,铝原子和银原子互扩散的结果.且随着银含量的增加,Zn-Al钎料的组织更加细化,有利于钎料力学性能的提高.这是由于银......
Brazing of directionally solidified TiAl-based alloy with Ti-Zr-Ni-Cu filler metalHE Peng,LIU Duo,FENG Jicai,and WANG Lun State Key Lab of Advanced Welding Production Technology,Harbin Institute of Technology,Harbin 150001,China摘 要:Brazing of directionally solidified TiAl-based alloy with Ti-Zr-Ni-Cu filler metal was investigated.For brazing,according......
-rich and Ti phases formed at the interface and commercially pure Ti base metal. However, no significant differences were observed between the joint system and the base material when brazing with TiCuNi filler. Key words: biomaterial; titanium; joining; brazing alloys; interface; microstructure; corrosion 1 Introduction Commercially pure (cp) Ti presents a number of desirable properties for several......
Dissolution behavior of Cu in Cu-Ag and Cu-P brazing alloys using weld brazingLI Yi-nan1, 2, WANG Chang-wen1, PENG Zi-long2, YAN Jiu-chun1, LIU Xue-song1(1. State Key Laboratory of Advanced Welding... of base metal Cu in the Cu-Ag and Cu-P brazing alloys using weld brazing was researched. The thickness loss of Cu foil in contact with Cu-P and Cu-Ag alloys at 800-920 °C was measured. And the dissolution......
