Description

A kind of titanium alloy ring billet weight grain refinement and grain deformation method

Technical field

The present invention relates to deformation method for grain refinement, especially a kind of titanium alloy ring billet weight grain refinement and grain deformation method.

Background technology

Titanium alloy due to the interference of the various extraneous factors such as personnel, equipment, environment, causes forging in process of production Cheng Zhong, it is easy to there is crystalline substance slightly, especially when finding brilliant thick after base punching terminates, typically only have selection to scrap, waste time and energy, And cause material waste.

The content of the invention

The applicant is directed to disadvantage mentioned above, has carried out Improvement, there is provided a kind of titanium alloy ring billet weight grain refinement and grain deformation Method.

The technical solution adopted in the present invention is as follows:

A kind of titanium alloy ring billet weight grain refinement and grain deformation method, comprises the following steps:

(1) heat:After the titanium alloy ring billet of coarse-grain is heated into 950~970 DEG C, 60min~90min is incubated;

(2) contracting ring:The titanium alloy ring billet of coarse-grain is put into upper and lower V-shape anvil, contracting ring is carried out, reduces internal-and external diameter, wall thickness Increase, it is highly constant;

(3) hot material melts down:Hot material melts down heating 40min~60min;

(4) fullering with the core bar:The ring billet that (2) step is obtained carries out fullering with the core bar, reduces external diameter, and internal diameter is constant, height Increase;

(5) hot material melts down:Hot material melts down heating 30min~50min;

(6) jumping-up:The ring billet that (4) step is obtained carries out jumping-up, ring billet height when jumping-up height to the 1st step heats;

(7) hot material melts down:Hot material melts down heating 40min~60min;

(8) saddle support reaming:The ring billet that (6) step is obtained carries out saddle support reaming, increases the internal-and external diameter of ring billet, wall thickness subtracts It is thin, it is highly constant;

(9) cool down:Room temperature is air-cooled to, checks grain size, competent collection product, unqualified repeat step (1)~(9).

Beneficial effects of the present invention are as follows:The titanium alloy ring billet weight grain refinement and grain deformation method, using contracting ring, mandrel pulls out It is long, axial jumping-up, saddle support reaming, the heavy deformation method of planar end surface, coarse grain is being repeated jumping-up, crystal grain is obtained in large deformation Refinement, eliminate or improve the brilliant thick problem of titanium alloy.

Brief description of the drawings

Fig. 1 is process chart provided by the invention.

Embodiment

Below in conjunction with the accompanying drawings, the embodiment of the present invention is illustrated.

(3) hot material melts down:Hot material melts down heating 40min~60min;

(4) fullering with the core bar:The ring billet that (2) step is obtained carries out fullering with the core bar, reduces external diameter, and internal diameter is constant, height Increase;

(5) hot material melts down:Hot material melts down heating 30min~50min;

(6) jumping-up:The ring billet that (4) step is obtained carries out jumping-up, ring billet height when jumping-up height to the 1st step heats;

(7) hot material melts down:Hot material melts down heating 40min~60min;

(8) saddle support reaming:The ring billet that (6) step is obtained carries out saddle support reaming, increases the internal-and external diameter of ring billet, wall thickness subtracts It is thin, it is highly constant;

(9) cool down:Room temperature is air-cooled to, checks grain size, competent collection product, unqualified repeat step (1)~(9).

Coarse grain is being repeated jumping-up, crystal grain refinement is obtained in large deformation, eliminate or improve the brilliant thick problem of titanium alloy.

Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to right It is required that in the case of the basic structure without prejudice to the present invention, the present invention can make any type of modification.
