Roll forging process can be divided into two types.
Some thin titanium alloy parts also adopt the advanced isothermal forging process at that time.
Forging process ensures best possible corrosion resistance.
The heat-dissipating body is manufactured by cold forging process, and the thermal conductivity is higher.
Forging process: 20% reduction, direct dial to Φ 580 mm x 6000 mm long;
A large number of references have mentioned that the"pitting" andvoids are prone to occur in the forging process of the alloy.
The mandrel forging process can be said to be the drawing length of shaft forgings.
A large number of engineering practices have proved that the performance of TA7 forging process is worse than other titanium alloys such as TC4 and TC11.
The forging process is more prone to cracking than other titanium alloys, and the crack growth rate is fast.
The defects may be caused by cracking due to the improper forging process, or there may be metallurgical defects such as inclusions, segregation, pores, etc.
During the forging process, the sucker rod ends are heated in induction furnaces to ensure optimal fatigue resistance of the forged zone.
Second, with neck butt welding, neck flat welding, socket welding, andthreaded flanges are generally made of forging or forging process.
Wrought is a forging process which exert pressure on a metal workpiece to produce plastic deformation, thus obtaining specific mechanical properties, shapes and sizes.
The forging temperature determines the microstructure of the titanium alloy andit is inevitable to produce β phase transformation during the forging process of titanium alloy.
The barrel is produced using a cold hammer forging process and features a chrome-lined bore with 6 right-hand grooves and a 1 in 178 mm(1:7 in) rifling twist rate.
This type of forging equipment has a low blow speed,a low instantaneous strain rate during the forging process, and the deformation heat generated is not very obvious.
Secondly in the alloy The blank and the finished die forging process are controlled by appropriate forging and cooling methods to suppress the occurrence of coarse a blocks in the microstructure.
When using a forging hammer with a faster forging speed toforge a titanium alloy, the central thermal effect in the forging process must be considered, and the billet cannot be continuously hit.
In the forging process, the TA7 bar has the largest deformation in the center of the bar and the slowest deformation heat diffusion, and the deformation temperature is the highest, so the cavity is most likely to occur during the large deformation process. .
The TC17 titanium alloy die forging is produced by a sub-beta forging process heating die forging at 40° C at the transformation point, and air cooling after forging. .
In the forging deformation of titanium alloy, the central part is generally a severely deformed area, so the center is the region with the highest temperature rise, andthe temperature rise of the central part is used as the main basis for formulating the forging process.
L TiN, TiO2, hardness and brittleness are very large, as shown in the following table,basically no plastic deformation ability, in the forging process is easy to form cracks, holes and other defects in the TiC. TiN TiC.
A large number of engineering practices have proved that TA7 forging process performance is worse than other TC4, TC11 and other titanium alloys, cracking is more likely to occur during forging than other titanium alloys, and the crack propagation rate is faster.
From November 21st to 22nd, industry experts, scientific research institutes, and entrepreneurs from the fields of titanium smelting andforging in China gathered in Baoji to discuss the smelting technology, forging process, precision casting and forming of large titanium, titanium and titanium alloys.
During the forging process of titanium alloy, due to the large instantaneous deformation rate(7~9m/s on the hammer) and high striking frequency, the internal flow stress of the alloy is too large, and a large amount of mechanical energy is consumed to be converted into internal heat in a short time.
The forging speed of such forging equipment is low,the instantaneous strain rate of the blank during the forging process is low, the deformation heat generated is not very obvious, and there is enough time for deformation.
For the forging process, firstly, during the ingot open-cast forging, appropriate high temperature homogenization treatment is adopted, and the micro-intracrystalline dendrite segregation in the columnar structure area of the ingot is improved and eliminated by homogenizing annealing or deformation recrystallization;
In the forging deformation of titanium alloy, the central part is a severely deformed area in general, so the center is the area with the highest temperature rise, and the temperature rise of the central part is taken as the main basis forformulating the forging process. When forging a titanium alloy with a forging hammer with a faster forging speed, the central thermal effect during the forging process must be considered, and the blank cannot be continuously hit.
The parameters are formed by improper control,so during the forging process, the appropriate deformation rate(forging equipment), heating forging temperature, pass deformation and cooling rate after forging need to be selected according to titanium alloy materials with different characteristics.
