The beneficial effects of the invention are as follows：
(1) addition element constituent content is than M (Mg):M(Si):M (Cu)=(14-16):(10-11):(20-22), due to
Addition rare earth Pr and Nd have diffusional delays, thus tri- kinds of elements of Mg, Si and Cu can total overall reaction first, separated out after timeliness strong
Change phase β ' (Mg2Si)、S’(Al2) and θ ' (Al CuMg2Cu) phase, makes precipitated phase be separated out completely from supersaturated solid solution, without surplus
It is remaining, the electron scattering in solid solution is reduced, distortion of lattice is reduced, increase conductance.
(2) rare earth aluminium alloy cable material disclosed by the invention has excellent electric conductivity, and also greatly improves
The tensile strength and elongation percentage of wire.Preparation method disclosed by the invention has carried out tuning proportioning to the various components of cable material,
Especially after equivalent addition rare earth Pr and Nd, M (Pr):M (Nd)=1:1.After Precipitation, precipitated phase is Al3(Pr,Nd)
Phase, this is mutually spherical shape under transmission electron microscope observing, with L12Cube core shell structure, average-size is that 12nm~30nm is left
It is right.Because Pr atomic ratio Nd atomic diffusion rates are slow, so foring centered on the aggregation of Nd atoms, Pr atoms are gathered in center
The core shell structure of outer rim, so Al3Pr inhibits the roughening for separating out precipitated phase from supersaturated solid solution to act on, Al3Nd is accelerated
Al3The precipitation of Pr phases, so element Pr and Nd have synergy.Nanoscale Al after being separated out after the timeliness3(Pr, Nd) phase
Can not only improve alloy strength, can also reduce the electron scattering in matrix so that alloy conductive rate increase.
(3) in heat treatment (solid solution+timeliness):530 DEG C~560 DEG C/18-22h+175 DEG C/6h, the solid solubility temperature of formulation and
Hardening constituent β (the Mg that time can generate all as cast conditions2Si)、S(Al2) and θ (Al CuMg2Cu) it is dissolved in matrix, noresidue reinforcing
Phase；Under 175 DEG C of peak value aging temps, all of hardening constituent separates out into β ' (Mg again2Si)、S’(Al2) and θ ' CuMg
(Al2Cu) intergranular precipitation hardening constituent, is evenly distributed on matrix surface, under peak aging time 6h, now all precipitation strengths
Mutually for size is the most tiny, and by the Al with synergy3(Pr, Nd) phase, it is suppressed that other precipitation phases are grown up
Roughening speed, improves alloy conductive and intensity.And combine the raising of free of contamination low frequency electromagnetic stirring technique highly significant
The electric conductivity of cable material, tensile strength, creep-resistant property be high and elongation percentage.Preparation process is simple simultaneously and environment is not made
Into pollution, it is adaptable to produce in batches.
The present invention strong Al-Mg-Si-Cu-Pr-Nd rare earth aluminum alloy power cable materials in preparing, its mechanical property refers to

Specific embodiment
Al-Mg-Si-type aluminum alloy be heat treatment can reinforced aluminium alloy, middle intensity high-conductivity aluminum alloy needs to combine alloy
Various enhancements mainly include refined crystalline strengthening, ageing strengthening.The Precipitation sequence of Al-Mg-Si system alloy is：Saturation is consolidated
Solution → Mg/Si elementides → GP (I) area (→ GP (II) area) → β ' phases → β ' phases → β phases.Hardening constituent is mainly in alloy
β’(Mg2Si) phase, precipitation strength is mutually carried out by the β ' of Precipitation disperse.In strong height lead aluminium alloy conductor and to have good power
Learn performance, it should control M (Mg/Si)<1.65, superfluous Si atoms can be separated out from matrix, reduce the distortion of lattice of matrix, favorably
In the raising of electric conductivity, Mg contents often increase by 1%, and resistance can increase by 0.54 × 10-8Ω m, so control M (Mg/Si) ratio
The size of alloy conductive performance can be controlled.Meanwhile, after adding Cu in Al-Mg-Si alloy, when Cu contents are more and M (Mg/
Si)<When 1.65, it is possible to create S ' (Al2) and θ ' (Al CuMg2Cu) phase.As M (Mg):M(Si):M (Cu)=(14-16):(10-
11):(20-22), element energy total overall reaction, precipitation strength phase β ' (Mg after timeliness2Si)、S’(Al2) and θ ' (Al CuMg2Cu) phase,
Precipitated phase is separated out completely from supersaturated solid solution, without residue, so reducing electron scattering in solid solution, reduce lattice abnormal
Become, the roughening speed of precipitation phase is also counteracts that, so that the electric conductivity and intensity of alloy have greatly improved.
Temperature and time with timeliness increases, and precipitation strength is met and be slowly roughened therewith, now adds rare earth element
Constituent content is than M (Pr):M (Nd)=1:1, by when efficiency separate out precipitated phase Al3(Pr, Nd) phase, this is mutually nanoscale phase,
Pr and Nd can form core shell structure due to the difference of diffusion velocity, slow down β ' (Mg2Si)、S’(Al2) and θ ' (Al CuMg2Cu)
The growth rate of phase, and by etc. than rare earth add, Al can be completely generated in solid solution3(Pr, Nd) phase, without remaining Pr and Nd
Atom, further reduces the electron scattering in solid solution, improves alloy conductive rate and intensity.
With reference to embodiment, the present invention is further illustrated, but is not limited thereto.
