Description
Technical field
The invention belongs to titanium alloy material processing technique fields, and in particular to a kind of control titanium alloy seamless tubular goods texture
Warm-rolling processing method and titanium alloy pipe.
Background technology
Titanium alloy pipe is applied to the fields such as Aeronautics and Astronautics, oil and sports goods, weldability, mechanical property, corrosion resistant
Corrosion energy, processing technology plasticity and mouldability are more excellent.The TA18 of industrially pure titanium and low alloying belongs to alpha titanium alloy, α
Mutually there is Patterns for Close-Packed Hexagonal Crystal, anisotropy is apparent, enhances tube wall using the anisotropy of texture, has weight to improving pipe performance
Want meaning.TA18 alloys drastically increase intensity compared with the pure titanium of tradition, and the advantage of cold-forming property is also retained,
Therefore as the preferred material of aviation hydraulic system tubing, the characteristics of deformation due to tubing preparation process, tubing is organized in footpath
To, it is tangential and it is axial show anisotropy, that is, form radial direction texture, tangential texture and axial texture.Tubing conventional detection
The mechanical property gone out is axial mechanical property, and the service condition of tubing is primarily radial and tangential.Tubing CSR
(contractile strain ratio) " contraction strain ratio " is an important indicator for evaluating its performance, in tubular object extruding
Deformation texture is the most important factor for determining CSR.Research shows to be conducive to carry for the texture based on radial direction by texture controlling
High CSR, therefore, how to obtain the favourable radial direction texture of high intensity as crystallographic structure, be to prepare high-quality titanium alloy tube
Material and the important guarantee for improving product qualification rate.
In tube rolling, texture type is mainly controlled by " subtracting wall and tube reducing ratio " Q values.Work as Q>1, texture is knitted for radial direction
Structure (favorable texture), and Q<1 texture is tangential texture, and the shape of roll and plug determines that tubing subtracts the Q during wall tube reducing
Value.
At present, titanium alloy pipe is substantially to be deformed texture by cold rolling processing, but is generated favorably by cold rolling
Radial direction texture need larger total deformation or need improve tubing Q values, even if in this way, after cold rolling, be unfavorable for tubing
The tangential texture proportion of performance also is difficult to reduce, and is influenced by equipment tonnage and material deformability, obtains Gao Jing
It is relatively difficult to the titanium alloy pipe of texture intensity, so as to affect further improving for CSR, it is difficult to obtain high intensity, have both
The titanium alloy pipe of plasticity and superior fatigue resistance, the qualification rate of product have much room for improvement.
The content of the invention
The present invention in view of the above shortcomings of the prior art, provides a kind of warm-rolling processing side for controlling titanium alloy pipe texture
Method, this method solve at present by cold rolling machining titanium alloy tubing be difficult to obtain at high proportion, the radial direction texture of high intensity asks
Topic improves the CSR of titanium alloy pipe, obtains high intensity, has both plasticity and the titanium alloy pipe of superior fatigue resistance, and
Method is simple, easily manipulation is made, produced suitable for industrial scale.
Texture enhancing is to ensure the important microstructure factor of titanium alloy pipe performance, and deformation texture is sent out in material stress
During raw plastic deformation, the slide surface and glide direction of crystal are rotated to stress axis, while adjoint twin, and polycrystal gradually tends to arrange
Row are consistent, show preferred orientation.It is not only related with the state of external force and deformation extent, the movable energy of atom also in by crystal
The influence of power.It in addition, the method for the present invention heating temperature is not high, will not aoxidize substantially, not yet reach stress relief annealing temperature, it is and cold
It rolls and compares, the intensifying factor in deformation process remains to retain.Moreover, heating temperature is not high, sensing heating and air resistance furnace
Meet warm-rolling heating requirements, other technique productions conditions are consistent with cold rolling, and method is simple, easily operated, suitable for scale
