One kind refinement Al-Si-Fe-Cu-Mg alloy structures and preparation method thereof
Technical field
The present invention relates to one kind refinement Al-Si-Fe-Cu-Mg alloy structures and preparation method thereof, especially belong to material and add Work technical field.
Background technology
Hypereutectic Al-Si Alloy is because with low-density, high specific strength, low thermal coefficient of expansion, heat conduction high and excellent Wear and corrosion behavior, be widely used in the fields such as Aeronautics and Astronautics, automobile.Substantial amounts of research shows in Hypereutectic Al-Si Alloy Middle a certain amount of Fe elements of addition can form AlSiFe intermetallic compounds, be conducive to improving the mechanical behavior under high temperature of alloy；Together When add a small amount of Cu, Mg element in the alloy and can form solid solution phase, tiny disperse phase is formed after Precipitation, can Improve the room-temperature mechanical property of alloy.Additionally, the addition of these alloying elements can also improve the heat endurance of alloy.But it is traditional Casting method due to slower cooling velocity, it is easy to form large-sized phase containing Fe (intermetallic compound phase) and Si phases (primary silicon phase and eutectic silicon) (as shown in Figure 1), the mechanical performance of severe exacerbation alloy hinders its extensive use.And Mould is also needed to during traditional handicraft melting, complex process takes more long.
The content of the invention
The present invention overcomes above-mentioned technique to limit to, and the present invention is proposed using selective laser smelting technology (Selective Laser Melting, SLM) prepare the Hypereutectic Al-Si Alloy of Fe contents high, and method by follow-up hot extrusion further improves conjunction The size of golden thing phase, so as to improve the mechanical performance of alloy.
In order to realize above technique effect, the preparation method of refinement Al-Si-Fe-Cu-Mg alloy structures of the invention is logical Cross following steps realization：
The preparation method of the refinement Al-Si-Fe-Cu-Mg alloy structures that the present invention is provided, comprises the following steps：
S1. by Al, Si, Fe, Cu and Mg melting, cast molding after degasification, slagging-off obtains the molten ingot casting matched somebody with somebody；The Al, The percentage by weight of Si, Fe, Cu and Mg be Si 19~22wt.%, Fe 4~5wt.%, Cu 2~3wt.%, Mg 0.5~ 1wt.%, balance of Al.Wherein, Al, Si, Fe, Cu and Mg are preferably industrial pure Al (99.7%), pure Si (99.5%), industry Pure Mg (99.7%), electrolysis Cu (99.97%), technical pure Fe (99.8%).Wherein, melting can be that metal charge is put into magnesia Crucible uses induction melting, and is stirred using graphite stirring rod during melting with the temperature of thermocouple assay melt in real time Mix, alloying element is uniformly distributed.Wherein, cast molding can be to be poured into metal die.Now, primary silicon presents many Side shape, intermetallic compound containing Fe is presented strip in as-cast structure, and average-size is at 165 μm.
S2. under inert gas shielding, after the molten ingot casting gas atomization matched somebody with somebody in step S1, sieving obtains alloyed powder End；The process of the gas atomization can use jet deposition equipment, and the molten ingot casting matched somebody with somebody is put into jet deposition fusion crucible, The angle of crucible is adjusted, atomizer is installed, equipment vacuumized, and pours the argon gas of 0.5atm and protected；Intensification makes ingot casting , then be transferred to alloy melt in the insulation crucible with uniform temperature by fusing, and melt is flowed out by high speed by catheter Into tiny drop, the material of catheter is boron nitride, and internal diameter keeps gas pressure between 3.0~3.5mm for gas atomization； Powder after atomization is collected, by after 250 mesh sieve, removing size powder bigger than normal.
S3. under inert gas shielding, the alloy powder in step S2 is prepared into institute using selective laser smelting technology Need the shaped alloys of Components Shape.Powder can be put into laser melting coating by the method for selective laser fusing to install sediment pan In funnel, the mobile device of funnel is debugged；Equipment is vacuumized, and pours a certain amount of argon gas as protective gas, reduced and close The oxidation of gold；Debugging laser parameter, starts experiment；Experiment terminates, and takes out shaped alloys, and powder is reclaimed.
S4. after the alloy components in step S3 being carried out into hot extrusion, the hypereutectic Al-Si-Fe- of the Fe contents high is obtained Cu-Mg aluminium alloys.The process of hot extrusion can be the size of adjustment extruding, and sample is put into copper pipe, then be put into copper pipe In hot-extrusion mold, the distance of seaming chuck is adjusted, open Hot Extrusion Equipment and apply a small amount of pressure；Hot Extrusion Equipment is taken out very Sky, and a certain amount of argon gas is poured as protective gas, reduce alloy and aoxidized in extrusion process；Mould and sample are added Heat, to design temperature after be incubated 10min start extruding；After extruding terminates, heating power supply is closed, after waiting mould to be cooled to room temperature Vacuum is unloaded, sample is taken out, is organized and behavioral observation.After hot extrusion, needle-like Al-Si-Fe intermetallic compounds are squeezed It is broken, 1.6 μm are reduced in size to, heat affected area is vanished from sight, and tissue becomes uniform.
Wherein, in step sl before the melting, first by Fe and Al in mass ratio 1:5, Cu and Al in mass ratio 1:2 systems Into Fe-Al and Cu-Al intermediate alloys.
Wherein, the smelting temperature is 800-850 DEG C in step sl, and smelting time is incubated to make all components after melting 20-30min, is kept stirring for during melting.
Wherein, in step s 2 the gas atomization when, fusion temperature control at 820 ± 10 DEG C, gas pressure during atomization Control is in 1.2MPa.
Wherein, the laser technical parameterses that the selective laser fusing is used in step s3 are that laser is Yb-YAG laser, Energy is 310-330W, sweep speed 1400-1600mm/s, 100-120 μm of sweep span, 30-60 μm of powdering thickness.
Wherein, the extrusion ratio of the hot extrusion is 9 in step s 4:1.
Wherein, the condition of the hot extrusion is vacuum environment in step s 4, and extrusion temperature is 300 DEG C~400 DEG C, extruding Pressure is 700MPa.
According to the Al-Si-Fe-Cu-Mg alloy structures prepared with upper type.As a kind of hypereutectic Al of Fe contents high- Si alloys.
Used as one kind of increases material manufacturing technology, selective laser smelting technology cooldown rate can reach 105-106K/s, long-range In existing preparation method, big cooldown rate can ensure to obtain tiny microstructure.Additionally, the method is in the fabrication process Do not need any mould, do not limited by scantling shape, manufacturing cycle is substantially reduced, as with wide application prospect Metal material preparation technology.
Follow-up hot extrusion, phase containing Fe and Si phase sizes further reduce in the presence of extruding force, in heating-up temperature Under effect, microscopic structure becomes uniform by diffusion.
In a word, by the comprehensive function of selective laser smelting technology and Hot-extrusion, phase size containing Fe in alloy by 165 μm are decreased to 1.6 μm, and size reduces two orders of magnitude；Si phase sizes are decreased to 2.5 μm by 46.5 μm.
