Rice beta-titanium alloy method, exploitation crystal grain more refine, well-balanced nanometer beta titanium alloy material；By adjusting each mandril in mold cavity
In different location, it can be achieved that beta titanium alloy material continuous severe plastic deformation, processing once be at best able to accumulate common extruding
9 deflections, and can be realized simultaneously the position (both horizontally and vertically) for changing local drastic deformation amount, it is final to obtain
Even grain size and tiny nanometer beta titanium alloy material, further increase its mechanical property.
The technical solution of the invention patent is: the present invention is a kind of channel pressings such as universal circle preparation nanometer beta-titanium alloy
Method, the preparation stage including blank, mandril adjusting stage and extrusion process.
The preparation stage of blank: mainly including that beta titanium alloy material prepares, cutting equipment, the material surface of beta-titanium alloy blank

The continuous severe plastic deformation of golden material.
Extrusion process: mandril is adjusted by external mechanical devices first and forms required type chamber, then squeezes beta-titanium alloy bar
Enter the type chamber adjusted to be squeezed, squeezes and be once at best able to accumulate the common deflection for squeezing 9 times, and can be simultaneously
Realize the position (both horizontally and vertically) for changing local drastic deformation amount, it is final to obtain even grain size and tiny nanometer
Beta titanium alloy material.
Using such scheme, by adjusting position of the mandril in the type cavity mould of the channels such as universal circle, extrusion molding goes out
The nanosizing and isometry of beta titanium alloy material tissue may be implemented in the beta titanium alloy material of different grain sizes, the new process.
The beneficial effects of the present invention are: the different positions by adjusting each mandril in the type cavity mould of the channels such as universal circle
The continuous severe plastic deformation, it can be achieved that beta titanium alloy material is set, squeezes and is once at best able to accumulate the common deformation for squeezing 9 times
Amount, while realizing the position (both horizontally and vertically) for changing local drastic deformation amount, the final even grain size and thin of obtaining
Small nanometer beta titanium alloy material, further increases its mechanical property.
