Description of drawings
Fig. 1 is the metallographic structure of GH4169 high temperature alloy deposited metal
Fig. 2 amplifies down 1000 times the shape appearance figure 3 of the as-welded metallographic structure of deposited metal white any any scan image mutually and on the matrix between dendrite in Fig. 2 for ESEM
Fig. 1 is the metallographic tissue of the high temperature alloy deposited metal of GH4169, and the GH4169 alloy is at standard heat place Mainly " and carbide forms with strengthening mutually γ ', γ by the γ matrix under the reason state. And deposited alloy is in the welding process In experienced the process that again fusing is solidified, γ ' originally or γ ", boride equates all to dissolve in the matrix, Its room temperature texture mainly is made of γ solid solution. Because cooling speed is very fast when deposited, γ solid solution is main The dendritic crystal that axle is very long.
Fig. 2 is that the as-welded metallographic of deposited metal is organized under the scanning Electronic Speculum and amplifies 1000 times, utilizes back scattering The morphology analysis that electronic atom ordinal number contrast principle is carried out, observe the tree interdendritic all adularescent generate mutually, The shape looks are the bone shape as shown in Figure 2. White selects one arbitrarily mutually and on the matrix in Fig. 2 Zhong Shu interdendritic Point is done scanning, and the result as shown in Figure 3. As seen from Figure 3, it is mutually rich to compare between crystalline substance white with matrix Collect a large amount of Nb and Mo element, illustrate that obvious Nb and Mo element segregation have taken place in the tree interdendritic, Nb and Mo content are higher. Can qualitatively judge white from the shape looks of white phase and element enrichment condition is mutually Laves phase (Ni, Fe, Cr)2(Nb, Mo, Ti). Crisp hard metallic compound Laves phase Existence must cause the mechanical properties decrease of alloy, therefore need to be at Laves phase fusing point more than 1093 ℃ Temperature heat-treat, to eliminate the Laves phase.
The specific embodiment
One, material melting
1, knotting crucible: pay for magnesia about 100mm first in moulding MgO crucible bottom, fill magnesia around and, with waterglass and magnesia powder knotting mouth of pot, fix again watering the road junction with pneumatic pick, crooked chisel compacting;
2, baking crucible: in the crucible that ties, put into a certain amount of pure iron, with small-power baking 1～2 hour;
3, weighing and the Ni that rechecked, Fe, Mo, Cr, raw material such as Nb, C are put into knotting and baked MgO crucible, Al, Ti are put into hopper, vacuumize then, power send electrical heating raw material to the crucible all to melt by smelting process;
4, after molten steel melts clearly, refining 1/4 hour;
5, have a power failure and in stove, charge into a certain amount of argon gas, send electricity again and adjust heating power molten steel temperature is remained near the fusing point, add alloy material (Al, Ti), and add the deoxidation of a certain amount of Mg-Ca alloy, sulphur, phosphorus;
6, adjust molten steel temperature near fusing point, charged heating is at the uniform velocity cast.
Two, heat treatment, forging, hot rolling
Carry out homogenising heat treatment watering the ingot casting that outpours: 1190 ℃ * 20h, air cooling, elements segregation such as δ phase that produces in the elimination casting process and Nb.Steel ingot is reheated, open and forge 1120 ℃ of temperature, final forging temperature: 930～950 ℃.Forging is of a size of 35mm * 35mm * 1600mm, is hot-rolled down to Φ 8mm wire rod, 1080 ℃ of hot-rolled temperatures after the reconditioning of outer surface process emery wheel.
Three, silk material processing
Carry out cold-drawn on the silk material dish circle drawing machine, cumulative deformation is no more than 50%, and intermediate annealing heat treatment is carried out on the protective atmosphere heat-treatment furnace, and temperature is 1020～1040 ℃, and the time by equal temperate zone is no less than 5 minutes.Pony-roughing pass silk material tolerance is by controlling at d ± 0.03mm, and the finished size tolerance is pressed
Control.The finished product wire size is d1.6mm.
Four, welding
Adopt the GTAW method to obtain overlay, the mother metal composition is Inconel 718 nickel-based high-temperature alloy sheet materials that generally use on the engineering, and thickness of slab is 3mm.Owing to remove mother metal fully during processing sample, so the mother metal composition does not have influence to deposited metal composition.
Concrete welding condition is as follows: welding current is 50A, and weldingvoltage is 12V, and protective gas is an argon gas, and shield gas flow rate is 10L/min, interlayer temperature＜150 ℃.
Five, post weld heat treatment
Find out (Fig. 1) from the metallographic structure of postwelding deposited metal, the main cause of Inconel 718 alloy weldability differences is the enrichments that generate Laves phase and the NbC of crystal boundary place.This is because Inconel 718 alloys when welding, alloy has experienced the process of solidifying again, and the existence of a large amount of niobiums has promoted Laves to form mutually, and these factors have caused the moulding of Inconel 718 alloy welding points, toughness to reduce, thereby it is lower to show as percentage elongation, and strength factor is not high yet.Therefore to carry out diffusion annealing heat treatment, reach interdendritic Nb element segregation mutually to eliminate Laves.Diffusion annealing has been eliminated fragility Laves that deposited metal forms mutually and the segregation of Nb in welding process, improved plasticity, passes through solid solution, timeliness heat treatment again, and " phase makes Inconel 718 alloys obtain intensive treatment to separate out γ ', γ.Concrete Technology for Heating Processing is:
Diffusion annealing: 1190 ℃ of insulation 12h, stove is cold; Solution treatment: 1030 ℃ of insulation 30min, water-cooled; Ageing Treatment: 720 ℃ of insulation 10h, air cooling.
