  • Patent number: 9994947
    Abstract: A method for producing a Ti-6Al-4V article, includes providing a work piece of a Ti-6Al-4V alloy having a beta-transus temperature; subjecting the work piece to a beta solution heat treatment process in a furnace with a vacuum at a temperature above the beta transus; quenching the work piece in the furnace using high pressure inert gas following the subjecting of the work piece in the beta solution heat treatment process; and subjecting the work piece to an overage heat treatment process in the furnace with a vacuum to overage the work piece following the quenching of the work piece. The work piece can be a bolt blank that is further manufactured into a titanium bolt with pre-machined wave form threads and wave form rolling process utilized to manufacture threads into the bolt blank.
