Abstract:
A method of brazing a substantially isomorphous beta phase only titanium base material selected from the group consisting of Ti-15 V-3 Cr-3 Sn-3 Al and Ti-13 V-11 Cr-3 Al, comprising the steps of:coating a braze material onto said base material, said braze material comprising substantially of only a Ti--Cu--Ni--Zr mixture comprising about 25-60 Ti wt. %, about 10-25 Cu wt. %, about 15-25 Ni wt. %, and about 15-25 Zr wt. %;initially heating said braze material and base material to achieve thermal stability between said braze material and base material, said initial heating being up to a temperature that is not more than a brazing temperature of said braze material;subsequently heating said braze material and base material up to said brazing temperature;forming a braze joint between said braze and base material.
