The invention provides a
machining and manufacturing method and application of heat-resistant
titanium alloy Ti60 wires. The method comprises the steps that Ti60
titanium alloy ingot castings are smelted by adopting a vacuum consumable
smelting technology; the smelted Ti60
titanium alloy ingot castings are forged into rods by adopting a free
forging technology; the Ti60
titanium alloy rods are finish-forged into thick rod blanks by adopting a finish
forging technology; the Ti60
titanium alloy thick rod blanks are rolled into straight strip wire blanks by adopting a hot rolling technology; surface treatment is conducted on Ti60
titanium alloy annealing wire blanks, and pre-oxidation oxidation film hanging treatment is conducted after defects on the surfaces of the wire blanks are removed; continuous high-temperature drawing deformation is conducted on the Ti60 titanium alloy wire blanks obtained after surface treatment by adopting a straight
wire drawing machine; the drawn wires are straightened by adopting
electric heating tension; and annealing heat treatment is conducted on the straightened wires, and finally
centerless grinding is conducted. According to the
machining and manufacturing method and application of the heat-resistant titanium alloy Ti60 wires, through combination of different heat
machining and
heat treating technologies, different matching combinations of the tensile strength, the
plasticity and the shearing strength can be obtained, and the heat-resistant titanium alloy Ti60 wires can be used for manufacturing advanced
aerospace fasteners such as rivets, bolts and nuts and are used in the temperature range of 600-650 DEG C.
