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......
on C-C composite were studied with the sessile drop method. The results showed that the wettability of these brazing fillers was improved with the increase of Cr content. Cr distributed at the interface of brazing filler/C-C composite and the formation of Cr23C6 phase was speculated. In the interface between Ni-33Cr-24Pd-4Si brazing filler and C-C composite, element Cr reacted with C-C to form Cr-C......
Interface structure and mechanical property of aluminum cooler vacuum brazing joint FENG Tao(冯 涛)1, LOU Song-nian(楼松年)1, WU Lu-hai(吴鲁海)1, LI Ya-jiang(李亚江)2 1. School of Materials... cooler is as follows. The cracks are initiated on the interface, then they expand under sub-critical state. When the stress on the remained zone reaches the maximum notch tensile strength of the brazing......
) in the vicinity of clad-core interface in annealed aluminum brazing sheet was investigated by EBSD technique. The results show that, with the increase of annealing temperature, the frequency of special boundaries.... The main objective of this work is to investigate the GBCD in the vicinity of clad-core interface of annealed aluminum brazing sheet by EBSD technique in order to supply experimental data and method......

EFFECT OF BRAZING TIME ON TiC CERMET/IRON JOINT BRAZED WITH Ag-Cu-Zn FILLER METAL J.C.Feng1,Z.R.Li1,L.X.Zhang1,H.J.Liu1 (1.National Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology,Harbin 150001, China) Abstract:The brazing of TiC cermet to iron was carried out at 1223K for 5-20min using Ag-Cu-Zn filler metal. The formation phase and interface structure......
brazing alloy. The morphology of brazed diamond grits and the interface structure between diamond grits and the matrix alloy are also presented. 2 EXPERIMENTAL A brazing technique of diamond... to the lower temperature and shorter holding period for brazing in the present work. The interface layer between the diamond grits and the matrix alloy has been revealed by SEM observation, as shown......
into the composite result in a local decrease of the base metal’s solid temperature. This causes partial melting at the interface of the base metal at the brazing temperature. It can be seen that the thickness...
