Description

Hydrogen roll compacting combination process is set for improve increasing material manufacturing titanium alloy tissue
Technical field
The present invention relates to material increasing fields, especially a kind of in particular to the improvement processing to titanium alloy tissue Hydrogen+roll compacting process is set for improve increasing material manufacturing titanium alloy tissue.
Background technology
The Heating style used during increasing material manufacturing includes laser, electric arc, plasma, electron beam etc., and is increasing material Exist in manufacturing process under the extraordinary metallurgy environment for quickly heating, being quickly cooled down, increasing material manufacturing metallurgical quality is poor, and tissue is coarse. It includes powder and silk material to be related to material forms, but regardless of light source and object form change, the metallurgical feature of process of setting It is essentially identical：Metal microcell is rapidly heated under the action of central heat source, rapid solidification, during subsequent layer by layer deposition After the multicycle, become cycle, acutely heating and cooling, adjacent layer or several layers of generations cycle remelting cooling, other sedimentary crystal grain Then handled by cycle low-grade fever.Remelting and low-grade fever processing are recycled, causes the microstructure of increasing material manufacturing metal component unique. During titanium alloy is the increasing material manufacturing of raw material, the crystal grain such as selective laser fusing, laser deposition molding are given birth to perpendicular to substrate interface Grow up to coarse Original β grain, column crystal, only a small amount of isometric or small grains occurs in bottom and top, formed extremely uneven Tissue signature, this coarse group be woven in the higher electron beam of energy density, electric arc increases in material technique, or even develop into and run through Column crystal.Nevertheless, very fast cooling be also brought inside coarse grain tiny lamella or acicular martensitic structure this Extraordinary particular tissues, this is also why increasing material manufacturing titanium alloy structure part deposited mechanical property is generally higher than casting even forging Principal element.
Around this problem, the prior art has carried out a large amount of pilot studys, from increasing material manufacturing technique itself, addition Reinforcing particle crystal grain thinning and the regulation and control that microstructure is carried out using magnetic field, electric field, ultrasound, laser, micro- forging etc., it is intended to solve Certainly increasing material manufacturing metallurgy problem：
1, realize that metallurgy improves to a certain extent by the regulation and control of increasing material manufacturing technological parameter.The prior art is from control The size for attempting to reduce column crystal in shape process parameter and subsequent heat treatment technique by technique is made.For example, The column crystal that P.A.Kobryn et al. has studied Ti-6Al-4V Alloy by Laser claddings generates rule, the results showed that high-temperature gradient Be conducive to the growth of column crystal with big cooling rate, high sweep speed can reduce the size of column crystal；
But it is to carry out tissue modulation, increasing material manufacturing laser, electron beam etc. from the angle of degree of supercooling to carry out control by technique High energy heat source heats, and solidification rate is in 0.1ms-1 to 5ms-1, on temperature gradient is very high-level at one, is joined by technique Number adjustment is difficult to realize refined crystalline strengthening；
2, it is the potential approach for realizing increasing material manufacturing structure refinement, U.S. Banerjee to add nucleating agent or alloy element Ti-TiB and Ti6Al4V-TiB composite materials are successfully prepared Deng using laser stereoforming technology, TiB reinforcements can be uniform It is distributed in deposited alloy, and can thinning microstructure to a certain extent.It is from increase equiax crystal by adding nucleating agent Come realize tissue improve, but add nucleating agent can influence alloying component, require stringent alloy to be also not suitable for alloying component；
3, by improving the raw material of increasing material manufacturing into the improvement of microstructure, such as Chinese patent The cycling hot hydrogen treatment process for the raising TC4 titanium alloy temperature-room type plasticities that CN201610032762.9 is proposed, carries out TC4 titanium alloys Secondary cycle sets hydrogen processing, i.e., carries out after once setting hydrogen processing to TC4 titanium alloys, then dehydrogenation, then carry out at secondary Pin hydrogen again Reason finally carries out solution hardening processing.Secondary Pin hydrogen processing method of the present invention improves the ratio of α phases and β phases in TC4 titanium alloys Example, increases the content of the preferable β phases of plasticity in alloy, reduces the content of α ' martensites, refined crystal grain, to make its room Warm plasticity is further improved；After secondary cycle hot stressing, the ultimate deformation for improving TC4 titanium alloys improves 22.1%, yield strength reduces by 11.1%, and yield tensile ratio reduces by 11.5%.But it has a disadvantage in that follow-up in TC4 alloys merely with hydrogen The effect of heat treatment process crystal grain thinning, and cannot utilize hydrogen circulation of melt deposition process promote elements diffusion and increase liquid/ Liquid/solid interface constitutional supercooling；Hydride forms and decomposes, sets hydrogen reduction resistance of deformation and promote dislocation motion and then formed to deform to lack It falls into, from multidimensional, multi-angle promotes non-spontaneous forming core, the effect of crystal grain thinning.
In addition, Zhao Jiaqi et al. sets hydrogen-hot isostatic pressing in Chinese patent CN201110419193.0 propositions improves casting Ti3The method of Al alloy microstructures, including：One, to casting Ti3Al alloys carry out heat and other static pressuring processes processing；Two, by heat etc. Ti after static pressure process3Al alloys carry out setting hydrogen processing；Three, opposed hydrogen treated Ti3Al alloys are dissolved, timeliness Processing；Four, vacuum annealing process is finally carried out.Conducive to heat and other static pressuring processes, casting Ti is repaired3Hole in Al alloys etc. lacks It falls into, improves the consistency of alloy；On the other hand again using hydrogen in casting Ti3Reversible alloying effect in Al alloys and each Kind phase transformation, refinement casting Ti3The microstructure of Al alloys makes up the adverse effect that coarse grains bring alloy property.But it is same Sample has a disadvantage in that merely with hydrogen in Ti3The effect of Al alloy follow-up heat treatment process crystal grain thinnings, and cannot be existed using hydrogen Circulation of melt deposition process promotes elements diffusion and increases the supercooling of liquid/solid Interface composition；Hydride forms and decomposes, sets hydrogen reduction Resistance of deformation simultaneously promotes dislocation motion and then forms deformation defect, and from multidimensional, multi-angle promotes non-spontaneous forming core, crystal grain thinning Effect.
Although three of the above method can improve increasing material manufacturing tissue to a certain extent, all there is a problem of it is corresponding, no Increasing material manufacturing titanium alloy tissue can effectively be improved.Therefore, it is possible to improve the process of increasing material manufacturing titanium alloy tissue urgently It excavates.
