Description
Technical field
The invention belongs to aluminium alloy treatment process more particularly to a kind of low temperature agings and multistage of super high Zn content aluminium alloy
Heat treatment process.
Background technique
In recent years, national defence was rapidly developed under national support energetically, was directed to the requirement day of material
Benefit is harsh.Structural material one of of the aluminium alloy as national defence weapon equipment field " lightweight ", also needs to adapt to this demand
Variation.Compared with the other structural materials such as steel and titanium alloy, although aluminum alloy materials have traditional advantage such as light,
The disadvantage of its intensity deficiency is equally significant；Currently, the mainstream research direction of structural material is by improving the intensity of alloy come real
The loss of weight target of existing material.Therefore, it while how playing aluminium alloy traditional advantage, compensates its defect, for aluminum alloy materials
Further development is obtained in national defence and application has great importance.
Currently, the superhigh intensity aluminium being most widely used in national defence.
It is Al-Zn-Mg-Cu alloy that alloy, which is 7000, usually has the features such as intensity is high, and alloying level is high.This is
The main means of column aluminum alloy materials strength enhancing are to control Zn/Mg ratio while improving Zn constituent content, and it is micro- to add other
Alloy element, it is however generally that, when main alloying element content increases to 12.5%, intensity is up to 800MPa or more, but high alloy
Constituent content brings the large scale of precipitate, the distribution of Gao Tiji accounting, and material is caused to have lost modeling in Developed fiber strength advantage
Toughness, this is also the main reason for 7000 line aluminium alloy plasticity of 800MPa grade is not high.
The influence of the second opposite aluminium alloy plasticity and toughness depends primarily on three aspects: quantity, pattern and size in aluminium alloy.
With the increase of the percentage by volume of the second phase, the second alternate average headway reduces, and material resists the drag of crackle Critical Cracking
It reduces, fracture toughness is greatly reduced.Second is similar spherical in shape or particle is tiny, then reduces to the illeffects of fracture toughness.For
The strong plasticity of matching ultrahigh-strength aluminum alloy, by controlling heat treatment process, making precipitate size and being distributed in certain level,
It is the privilege path for obtaining high comprehensive performance.The Zn and alloying element content of superelevation cause aluminium alloy alloying element in solid solution to be difficult to
Solid solution completely, generally there are part indissoluble phases, it is difficult to form supersaturated solid solution, while main Precipitation hardening constituent
For MgZn2 since Zn, Mg alloying element content are high, Stages of Aging is extremely sensitive to timeliness temperature and time after solid solution, conventional
Artificial aging temperature will lead to the part forming core of hardening constituent unevenly and part is grown up, and reduces integral material plasticity.
Patent: CN201710160142.8 discloses the founding and heat treatment process of a kind of high Zn constituent content aluminium alloy.
This method has formulated a kind of heat treatment process of three-stage solution+three-step aging, obtains tensile strength and is up to 790MPa, extends
The aluminium alloy capability of rate 7% or so.It is Zn:9.8~11.2 that the patent, which only gives alloying element content,；Mg:1.6~2.4；
Cu:1.2~2.1；Zr:0.08~0.20；Fe≤0.15；Si≤0.1；Mn≤0.05；Cr≤0.05；Ti≤0.05；Al surplus
Aluminum alloy heat treatment process, but the aluminium alloy for being more than 11.2% for more high alloy constituent content, especially Zn content is uncomfortable
With, meanwhile, it is more than 800MPa, common 800MPa grades of Tensile Properties of Aluminum Alloy of elongation percentage >=5% which, which does not obtain intensity,.
It is suitble to the aluminum alloy high-strength plasticity of high alloy constituent content to be heat-treated work it can be seen that how to formulate from more microcosmic level
Skill is one of the important directions of next-generation higher intensity aluminium alloy research and development.
