Predicting the hardness and solute distribution during brazing of Ti-6Al-4V with TiZrCuNi filler metals

A modelling approach for the hardness and solute distribution during brazing of Ti-6Al-4V with Ti-Zr-Cu-Ni amorphous fillers is presented. The model for hardness incorporates main strengthening mechanisms in α+β alloys and a solid-state diffusion model is employed to describe redistribution of Zr, Cu and Ni in the joints.
