Advanced Metallic Materials with Amorphous Structure Used for Resistance Brazing Joints
2015
In this paper will be presented experimental researches on development advanced alloys with amorphous structures based on Ni and Cu for resistance brazing joints. The main advantages of these amorphous alloys in shape of ribbons are their ductility and flexibility. These ribbons are obtained by ultra-rapid cooling of the melt. Using resistance brazing process, were obtained brazing joints of stainless steel and copper strips. The joints were mechanical and structural analysed. It was performed mechanical shear test on the brazed joints to establish the shear strength of the joints, and also it was performed structural investigation to emphasize the microscopic structure and the structural transformations that take place in the base material and brazing alloys during the brazing process.
