ABSTRACT:
A method of brazing a Ti-15 Mo-3 Nb-3 Al-0.2 Si base material includes the steps of coating a braze material onto a base material. The braze material comprises substantially only a Ti--Cu--Ni--Zr mixture, with the mixture comprising about 40 wt % Ti. In particular, the braze material may comprise 40Ti-20 Cu-20 Ni-20 Zr. A following step includes heating the braze material and then forming a braze joint between the braze and base materials. The heating step can occur from about 760 to 932.degree. C. and over 15 to 90 minutes.
