This study deals with the vacuum TLP (Transient Liquid Phase) brazing of aluminum alloys applied to the manufacture of heat exchangers. Thus, the microstructure evolutions of 3003 (Al-Mn) and 4004 (Al-Si-Mg) alloys during the whole assembly process are studied. Firsty, model samples are heat treated in laboratory. The phase transformations and the solid state diffusion between the filler alloy and the base alloy are studied. The results are compared to thermodynamic predictions obtained with both Thermo-Calc and DICTRA softwares. We conclude that these tools are reliable at temperatures above 400°C. The fusion path of the filler alloy is described. It is shown that a Si enriched liquid is formed at the clad surface. On a second time, tests ...
