Abstract
The invention relates to a high-performance casting aluminum alloy suitable for spaceflight products. The high-performance casting aluminum alloy which is reasonable in chemical composition proportion and meets technical indexes is confirmed by optimizing the chemical composition of casting aluminum alloy on the basis of ZL107 aluminum alloy material. The element components and proportions (weight percent) of the alloy are as follows: 5.5-7.5 percent of Si, 0.05-0.35 percent of Mn, 3.5-4.5 percent of Cu, 0.05-0.2 percent of Cd and the balance Al. The existence of impurities is allowed in the high-performance casting aluminum alloy; when metal mold casting is adopted, the sum of impurities is less than or equal to 0.4, wherein Fe is less than or equal to 0.2; and when sand mold casting is adopted, the sum of impurities is less than or equal to 0.3, wherein Fe is less than or equal to 0.2. The casting aluminum alloy provided by the invention is formed by smelting the element components of the alloy in proportion. After T5 state thermal treatment is performed, the mechanical property is as follows: the tensile strength Sigma b is more than or equal to 300MPa, the elongation Delta is more than or equal to 1.5% and the hardness HB is more than or equal to 110.
Description
Technical field:
The present invention relates to a kind of y alloy y, particularly a kind of y alloy y that is applied in aviation field.
Background technology:
Y alloy y is on the basis of fine aluminium, to add other metal or non-metallic element; It had both kept the fundamental property of fine aluminium; And because alloying and thermal processes act; Make duraluminum have good comprehensive performances (high like mechanical property, corrosion resistance is strong, and is strong to various technological process flexibility).The density of y alloy y is littler than cast iron and cast steel, and intensity is higher.Therefore bearing employing aluminum alloy casting under the same load-up condition, can alleviate the weight of structure, so in aircraft industry and power machine and Transport Machinery manufacturing, aluminum alloy casting is used widely.Along with the progress of aircraft industry, it has proposed particular requirement to some performance of products, and the performance of existing duraluminum can not meet design requirement.
Summary of the invention:
The present invention is the basis with the ZL107 aluminum alloy materials, through carrying out the Chemical Composition optimization of y alloy y, has confirmed that a kind of Chemical Composition reasonable ratio also can satisfy the high performance casting duraluminum of technical indicator.
The present invention realizes through following technical scheme:
A kind of high performance casting duraluminum that is applicable to space product, its alloying element composition and proportioning (weight percent) be as follows:
Allow impurity to exist among the present invention, when using permanent mold casting, impurity summation≤0.4, wherein, Fe≤0.2; When using sand mold casting, impurity summation≤0.3, wherein, Fe≤0.2.
Y alloy y of the present invention forms through the melting of above alloying element proportioning components, carry out the thermal treatment of T5 state after, aspect mechanical property, reach: tensile strength sigma b >=300MPa, elongation δ >=1.5%, hardness HB >=110.
Embodiment:
When filling with substance is the basis with 99.70% fine aluminium, adds metals such as silicon single crystal, alumal, aluminum-copper alloy, cadmium metal simultaneously, and its ratio is: silicon single crystal 7%, alumal 2%, aluminum-copper alloy 8%, cadmium metal 0.2%.Aluminium liquid refining treatment adopts three-in-one refining deterioration agent and cooperates Argon to handle, and the stokehold is carried out composition through direct-reading spectrometer and detected, and pours into a mould after meeting the composition requirement, and tapping temperature is controlled at 720 ± 10 ℃.Its fusion process is: feed-dissolve-refining-composition adjusts-comes out of the stove cast.Carry out carrying out composition and mechanical property detection after the thermal treatment of T5 state.
Allow impurity to exist among the present invention, when using permanent mold casting, impurity summation≤0.4, wherein, Fe≤0.2; When using sand mold casting, impurity summation≤0.3, wherein, Fe≤0.2.
Claims (2)
1. high performance casting duraluminum that is applicable to space product is characterized in that: its alloying element composition and proportioning (weight percent) as follows:
2. a kind of high performance casting duraluminum that is applicable to space product according to claim 1, it is characterized in that: foreign matter content is in the duraluminum: when using permanent mold casting, impurity summation≤0.4, wherein, Fe≤0.2; When using sand mold casting, impurity summation≤0.3, wherein, Fe≤0.2.
