Description
One, technical field
The present invention relates to the hot-work field, specifically is a kind of titanium alloy local loading and shaping microtexture control method.
Two, background technology
In the multiple microtexture of titanium alloy, ternary tissue has good comprehensive performances, and obtaining to have the ternary titanium alloy forging of organizing is the target of pursuing in producing.The principal character of ternary tissue is to organize medium axle α phase content between 10%～20%, and equiaxial alpha content crosses that I haven't seen you for ages and reduce the plasticity of material, and too high levels then can reduce the high-temperature behavior and the fracture toughness property of material.Local loading is a kind of forming technology of producing the titanium alloy member by many fire time nonaffine deformations, because the required fire of processing is inferior many, everywhere distortion is very inhomogeneous again on the forging of every fire time, the loading zone that not only has direct stress deformation, also there is the non-loading zone that does not deform, and between takes place by the zone of transition of dynamic deformation, and this makes to Microstructure Control difficulty more.At present, domestic and international control method to equiaxial alpha content mainly contains two kinds:
(1) titanium alloy is forged post-heating and is heat-treated to the following 10-20 of transformation temperature ℃ nearly β temperature at the following 40-50 of transformation temperature ℃ two-phase region forging and molding.This method such as can control preferably at the content of axle α phase, but deformation does not take place or the material of miniature deformation only takes place in heat, cause tissue abnormalities to be grown up possibly, thereby this method is not suitable for the very big local loading process of nonaffine deformation degree.
(2) titanium alloy is heated to the following 10-15 of transformation temperature ℃ and carries out nearly β and forge.Because the local loading process distortion is inhomogeneous, the broken nodularization of regional strip α that deflection is big raises equiaxial alpha content, this makes the control of equiaxial alpha content become difficult, and, will cause crystal grain thick in the empty burning of nearly β temperature for a long time, degradation because local loading processing fire is inferior more.
Three, summary of the invention
For overcoming the uneven deficiency of forging equiaxial alpha content that exists in the prior art, the present invention proposes a kind of control method of local loading and shaping equiaxial alpha content.
The present invention blank is changed forge and preliminary shaping after, through obtaining the shaping forging after isothermal local loading and shaping, finishing and the thermal treatment, the parameter by the control local loading and shaping realizes the control to equiaxial alpha content, specifically forming process is as follows:
The first step, blank change forging
Titan alloy casting ingot is in the above cogging of transformation temperature, and ingot casting is heated to T
β+ (50～100 ℃), deflection 50%～60% is forged the back water-cooled, to improve the metallurgical quality of material, improves the tissue and the homogeneity of ingredients of material; The blank that obtains after the cogging is heated to T
βThe two-phase region of-(40～50 ℃) changes forging, and deflection 50%～60% is forged the back water-cooled, to obtain tiny equiaxed structure or bifurcation tissue.
Second step, preformed blank preparation
To change the blank appearance parcel adiabatic cotton after the forging, be heated to T
β-40 ℃, adopt flat-die forging to carry out base, when the many fire of needs time base, after after each fire processing blank being wrapped up adiabatic cotton, melt down heating again, to increase the deflection of every fire, reduce the processing fire, suppress microstructure coarsening.
The 3rd step, isothermal local loading and shaping
Local loading divides two passages to finish, and each passage divides two loading steps to finish.Patrix is divided into two of internal mold and external molds, perhaps is divided into two limit moulds and middle mould totally three modules; With internal mold and external mold, perhaps two limit moulds and a middle mould are installed on the upper bolster independently of one another.In first passage; at first apply distortion and finish first and load the step being positioned at blank under its vertical projection with internal mold or middle mould; with external mold or two limit moulds other parts of blank are applied distortion then and finish second and load the step, deflection is 70%～80% of a total deformation.After finishing two loading steps of this passage, change second passage over to, repeat the loading method of first passage, finish the distortion of forging, deflection is 20%～30% of a total deformation.
The specific implementation process of local loading and shaping is:
First passage first loads the step: internal mold or middle mould are installed, mold heated is arrived T
β-60 ℃, blank is heated to T
β-(40～50 ℃) carry out local loading with internal mold or middle mould to the blank that is positioned under its projection, and the speed of depressing is 0.2～0.4mm/s, and the relative deformation equals 70%～80% of total deformation.Finish after the loading with blank depanning water-cooled dismounting internal mold or middle mould.
First passage second loads the step: external mold or two limit moulds are installed, mold heated is arrived T
β-60 ℃, blank is heated to T
β-(40～50 ℃) carry out local loading with external mold or limit mould to the blank that is positioned under its projection, and the speed of depressing is 0.2～0.4mm/s, and the relative deformation equals 70%～80% of total deformation.Finish after the loading with blank depanning water-cooled dismounting external mold or limit mould.
Second passage first loads the step: internal mold or middle mould are installed, mold heated is arrived T
β-60 ℃, blank is heated to T
β-(40～50 ℃) carry out local loading with internal mold or middle mould to the blank that is positioned under its projection, and the speed of depressing is 0.2～0.4mm/s, and the relative deformation equals 20%～30% of total deformation.Finish after the loading then with blank depanning water-cooled.
Second passage second loads the step: external mold or two limit moulds are installed, mold heated is arrived T
β-30 ℃, blank is heated to T
β-(15～20 ℃) carry out local loading with external mold or limit mould to the blank that is positioned under its projection, and the speed of depressing is 0.2～0.4mm/s, and the relative deformation equals 20%～30% of total deformation.
The 4th step, finishing
Each piecemeal mould acts on blank simultaneously during finishing.Each piecemeal mould is installed in the whole patrix of formation on the upper bolster simultaneously, and to the forging finishing, finishing adopts the pressing machine pressurize to finish with whole patrix, 6000 tons of pressurize tonnages, and the dwell time is 10min～15min.With this understanding, material generation superplastic deformation can reduce forming defects.
The 5th step, thermal treatment
Take out the workpiece water-cooled after the forging immediately, adopt the thermal treatment process of recrystallization annealing then, workpiece is heated to recrystallization temperature, insulation 2～3h, air cooling.
The 6th step, nondestructive testing.
The distribution of technical scheme of the present invention by control temperature of local loading procedure and deflection realizes the control to axle α phase volume fractions such as forging.During local loading first passage, forging is forged gross distortion under the temperature in routine, makes forging keep original tiny axle such as grade or bifurcation tissue; Second passage first loads to go on foot still to forge under the temperature in routine is out of shape, little to the influence of forging tissue; Second passage second loads the step, it is last fire of local loading, forging is forged under the temperature at nearly β small deformation is taken place, reduced the nonaffine deformation degree under nearly β forging temperature, suppressed α phase spherodization, thereby suppressed to wait the increase of axle α phase volume fraction, also made and to wait axle α phase volume fraction even, the generation that the while tissue abnormalities of also having avoided empty burning to cause is grown up.Adopt technical scheme of the present invention, axle α phase volume fractions such as forging are controlled between the 10-20%, and axle α phase volume fraction such as different sites differs in 5% on the forging, waits a α crystal grain and β crystal grain all evenly tiny, there are not alligatoring, uneven homogenize and the phenomenon of growing up unusually, good mechanical performance.
