Description
Technical field
The invention belongs to metal material field, there is provided a kind of piston strengthens aluminum alloy materials with difficult molten metal.
Background technology
At present, truck, engineering machinery, railway locomotive and electromotor peculiar to vessel are all to high-power, high load capacity side
To development, reinforcing degree is improved constantly, and emission request is more and more stricter.Ge Jia pistons company is all in the new work of independent research and development at present
Plug material, on the basis of the tangible alusil alloy of groundwork, ambrose alloy content is improved, to expect that appearance is more in piston tissue
Alloy phase, mutually improves the resistance to elevated temperatures of piston material by alloy, and titanium, zirconium, vanadium mainly refines piston tissue, while
There is potentiation.But presently done alloying, determines the elevated temperature strength of material, as 300 DEG C, 350 DEG C of increase rates have
Limit, is only capable of 10% or so are improved on the basis of original, and material is less about 5% in 350 DEG C of high temperature above intensity increase rates
Left and right.Electromotor requirement of the upgrading to piston material can not be met, part producer is forced, using forged steel material piston, both
Increasing cost increases piston weight again, increases electromotor energy consumption, does not meet the development trend of green energy conservation.
The content of the invention
The purpose of the present invention is exactly for asking of solving that existing alloy material can not meet that part worked in high temperature environments
A kind of topic, there is provided formula by adding difficult molten metal in aluminium alloy, improves the elevated temperature strength of material；And to infusibility solution gold
Addition of the category in aluminium alloy, it is proposed that solution.Solve current alloy material piston can not be met in electromotor
The problem worked under higher temperature, explosion pressure environment, elevated temperature strength are obviously improved, and meet electromotor and upgrade to piston material
The requirement of material.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of piston strengthens aluminum alloy materials, including following component with difficult molten metal：Silicon Si:10.0-25.0%, copper
Cu:1.5-6.0%, nickel:1.0-3.5%, magnesium Mg:0.2-1.6%, ferrum Fe:0.2-1.0%, titanium Ti:0.05-0.3%, phosphorus P:
0-0.05%, manganese Mn:0.05-0.6%, zirconium Zr:0.05-0.3%, vanadium V:0.05-0.3%, molybdenum Mo:0-0.6%, tungsten W: 0-
0.6%, niobium Nb：0.005-0.6%, tantalum Ta：0-0.6%, strontium Sr:0-0.05%, balance of aluminum Al.
Present invention also offers a kind of piston strengthens the preparation method of aluminum alloy materials with difficult molten metal, including following step
Suddenly：
1）Nickel, ambrose alloy, ferronickel or ambrose alloy ferrous alloy are prepared, infusibility solution metal niobium and molybdenum, tungsten are added in above-mentioned alloy
Or one or more in tantalum, it is made into intermediate alloy；
2）Intermediate alloy is added into aluminium alloy, aluminium alloy temperature 580-630 DEG C, using the stirring of mechanically or electrically magnetic up in
Between alloy melt completely, obtain final product.
Preferably, step 1）In, the method for the preparation production nickel, ambrose alloy or ni-fe-based alloy is：Can be in power frequency
Various metals are added in stove, frequency conversion furnace or intermediate frequency furnace disposably；Or such as nickel, copper, the fusing of ferrum of meltable solution is first carried out, treat that nickel etc. melts
Change adds refractory metal after finishing and is melted, and is warming up to 1580 DEG C～1680 DEG C, is incubated 0.5～6 hour, treats refractory metal
After fully melting, then casting ingot-forming.
Preferably, step 1）In, nickel, ambrose alloy or ni-fe-based alloy are nickel tungsten, nickel-molybdenum alloy, ickel-niobium alloy, nickel
Tantalum alloy, the combination of one or more in ambrose alloy tungsten, ambrose alloy ferrum niobium or ferronickel tantalum.
Preferably, step 2）In, the mass ratio of the nickel, ambrose alloy or ni-fe-based alloy and aluminium alloy is 0.01～1:
1。
Piston hardly possible molten metal prepared by arbitrary above-mentioned method strengthens aluminum alloy materials in piston blank is prepared
Using.
The invention has the beneficial effects as follows：
1. added using two-step method, refractory metal made into nickel, ambrose alloy or ni-fe-based alloy first, such as nickel tungsten,
Nickel-molybdenum alloy, ickel-niobium alloy, nickel tantalum alloy, ambrose alloy tungsten, ambrose alloy ferrum niobium or ferronickel tantalum etc. various alloys, but iron-holder in alloy
Control below 30%, reason is that the iron content in piston alloy is too high, needle-like ferrum can be formed, Tensile strength is significantly
Decline.Second step is that nickel-base alloy is added in aluminium alloy, using strength mechanical agitation or electromagnetic agitation mode, more than acceleration
Melting of the alloy in aluminium alloy.Aluminium alloy addition tungsten, niobium, tantalum refractory metal, fusing in being directly added into aluminium alloy is extremely difficult
, fusing is easier in aluminium alloy as refractory metal titanium, zirconium equally, refractory metal vanadium is also easier to by becoming vananum
Aluminium alloy is fused into, addition titanium, zirconium, v element are more universal at present, the content of non-this patent protection；And tungsten, molybdenum are needed by length
Time is melted in high temperature aluminium alloys, can just be fused in aluminium alloy, but causes substantial amounts of oxidization burning loss；And melting niobium,
Tantalum metal, in aluminium alloy, long-time cannot also melt, above hardly possible molten metal.
2. alloy heat stability is good, and intensity is high, is adapted to run at high temperature.
