Abstract
The invention relates to a light metal alloy.
Description
The present invention relates to cast aluminium alloy, particularly be applied to the alloy of vehicle frame.Usually, the alloy that is used for this purpose mainly is a fused hypoeutectic Al-Si alloy, for improving intensity, contains a small amount of Mg in the AlSi alloy, for example: AiSi7Mg or AlSil1Mg.Under individual cases, also use AlSi (Mg, Cu) alloy, but because the corrosive property of this alloy can only be used for special application.(Ti, Mg) also there is identical problem in alloy system to the AlCu that intensity is the highest in common alloy.Equally, the application of AlMg alloy in frame part is limited.Other alloy system as AlZn or AlLi, does not adopt in vehicle frame.
Parts by above-mentioned alloy manufacturing obtain desired characteristics through two warm processing usually.
Generally all there is such defective in existing alloy system: only can obtain limited stress-strain ratio.Above-mentioned intensity is higher contains the Cu alloy and often can not use because of corrosive property.AlMg alloy casting difficulty height makes it use (geometrical shapies of parts) and is restricted.
Therefore, the purpose of this invention is to provide a kind of higher strength of materials that has, the alloy that also has sufficiently high elongation at break characteristic simultaneously is used in particular for the application in the vehicle structure.For example in vehicle frame is used,, need possess above-mentioned characteristic simultaneously in order to withstand abominable working conditions.Simultaneously, this alloy must have fabulous cast, can not propose excessive demand to melting treatment and metal recovery because of alloying constituent simultaneously.
According to the present invention, realize above-mentioned purpose by the cast aluminium alloy that contains following at least 5 kinds of alloying constituents:
Si:2.5 weight % to 3.3 weight %, preferred 2.7 weight % to 3.1 weight %;
Mg:0.2 weight % to 0.7 weight %, preferred 0.3 weight % to 0.6 weight %;
Fe:＜0.18 weight %, preferred 0.05 weight % to 0.16 weight %;
Mn:＜0.5 weight %, preferred 0.05 weight % to 0.4 weight %;
Ti:＜0.1 weight %, preferred 0.01 weight % to 0.08 weight %;
Sr:＜0.03 weight %, preferred 0.01 weight % to 0.03 weight %;
Other:＜0.1 weight %;
Under the above-mentioned condition, surplus is Al, and making summation is 100 weight %.
Alloy according to the present invention has the stress-strain ratio that the routine casting aluminium alloy that do not contain Cu can't obtain.Particularly in the pressure adjuvant casting method, for example, low pressure-back-pressure-chill casting method can obtain better mechanical characteristics by good cast structure.
Make this alloy grain refinement help improving performance.
For obtaining above-mentioned advantage, or further improve, advantageously, cast components is particularly heat-treated with following parameter through Overheating Treatment:
Solution annealing: handle 1～10h for 490 ℃ and 540 ℃.
Tempering: handle 1～10h for 150 ℃ and 200 ℃.
Yet, concerning some is used, advantageously, only handle, as is generally known T4, T5 or 0 attitude aluminium alloy in isothermal tempering.
Except that above-mentioned advantage, also have other advantages according to alloy component of the present invention, that is,, can significantly improve erosion resistance owing to do not contain Cu and Cn alloying constituent.This product cost is relatively low, because these alloy additive as rare earth metal, do not have a kind of meeting that the cost of this product is improved, can adopt general melting treatment, does not need extra-pay to carry out Separation and Recovery.
Fabulous stress-strain is than fabulous cast is provided.At first, the getable foundry goods of this cast characteristic can be avoided major defect (being sand holes), and secondly, microtexture improves, and, at utmost reduces the quantity of internal porosity that is, and such pore can reduce elongation at break.
Following table provides examples of numeric values (table vides infra):
| R mTensile strength [MPa] | R p0.2Yield strength [MPa] | A 5Elongation [%] | |
| Gravity chill casting as-cast condition | 250 | 140 | 13 |
| Gravity chill casting thermal treatment T6 (540 ℃, 7h, 160 ℃, 8h) | 320 | 260 | 5 |
| Pressure assist chill casting thermal treatment T6 (540 ℃, 7h/160 ℃, 6h) *Only provide accurate values where necessary | 370 | 300 | 11 |
