Si diffusion behavior during laser welding-brazing of Al alloy and Ti alloy with Al-12Si filler wire CHEN Shu-hai(陈树海), LI Li-qun(李俐群), CHEN Yan-bin(陈彦宾), LIU De-jian(刘德健) State Key... (Ti-6Al-4V) with rectangular CO2 laser spot and with Al-12Si filler wire, element Si enriches at the interface between Ti substrate and the filler metal. It is found that the Si diffusion behavior has......
Diffusion behavior of silicon at interface ofAl clad sheet and joint formationDusan P. Sekulic2,GAO Feng(高 峰)1,2, QIAN Yi-yu (钱乙余)1, ZHAO Hui(赵 惠)2(1. State Key Laboratory of Advanced Welding... behavior of silicon in the brazing clad sheet was studied. It is interesting to notice that the residue clad appears after the brazing process, regardless of the brazing conditions. Diffusion coefficients......
