Abstract
The present invention relates to a kind of casting.
Description
Technical field
The present invention relates to a kind of casting especially as chassis application.
Background technology
Al alloys hypoeutectic for chassis application field generally use, with 7-12 weight %Si contents.It is cold in gravity
Generally use alloy AlSi11Mg, the generally use alloy AlSi7Mg in low-pressure chill casting in hard casting.By WO2007/
025528A2 and WO/2009/059593 is known containing AlSiMg alloys few Si, and the alloy is relative to above-mentioned general AlSi castings
Alloy has the mechanical performance being obviously improved.
Invention content
Based on the prior art, it is an object of the present invention to which the mechanical performance for casting further improves by few containing Si
The casting that Al alloys are constituted.
According to the present invention, which is realized by the casting being made of Al casting alloys, which contains at least
Five following alloy compositions
Si：2.5 to 3.3, preferably 2.7 to 3.1 weight %
Mg：0.2 to 0.7, preferably 0.3 to 0.6 weight %
Fe：＜ 0.18, preferably 0.05 to 0.16 weight %
Mn：＜ 0.5, preferably 0.05 to 0.4 weight %
Ti：＜ 0.1, preferably 0.01 to 0.08 weight %
Sr：＜ 0.03, preferably 0.01 to 0.03 weight %
Cr：0.3 to 1.3, preferably 0.4 to 1.0, particularly preferred 0.5 to 0.8 weight %
It is other：0.1 weight % of ＜,
And 100 weight % are supplemented to Al respectively, medium casting carried out between 150 to 240 DEG C heat aging processing 15 to
120 minutes, preferably 15 to 60 minutes, it is 20 to 55 minutes particularly preferred, very particularly preferably 30 to 55 minutes and absolutely especially
It is preferred that between 30 to 45 minutes.
It can be beneficial that casting carries out heat aging processing 15 to 120 minutes, preferably 15 to 60 between 170 to 230 DEG C
Minute, it is 20 to 55 minutes particularly preferred, very particularly preferably 30 to 55 minutes and absolutely particularly preferred between 30 to 45 minutes.
Can appropriately, casting carries out heat aging processing 15 to 120 minutes, preferably 15 to 60 between 200 to 220 DEG C
Minute, it is 20 to 55 minutes particularly preferred, very particularly preferably 30 to 55 minutes and absolutely particularly preferred between 30 to 45 minutes.
Other advantage can be that casting carries out solution annealing 1 before heat aging processing between 490 and 550 DEG C
To 10 hours, preferably 5 to 9 hours, it is 6 to 8 hours particularly preferred.
It can be beneficial that progress solution annealing 1 to 10 is small between 530 and 550 DEG C before heat aging processing for casting
When, preferably 5 to 9 hours, it is 6 to 8 hours particularly preferred.
Above-mentioned heat treatment leads to significantly further to improve the mechanical performance through pouring into a mould component or casting.
Chassis is applied, especially for the component that wheel is oriented to, generally improves mechanical features value.
Alloy according to the present invention can contain the impurity by restriction of production, such as Pb, Ni, Zn etc., as this field is special
Industry personnel are generally known.These impurity belong to other alloy compositions.
Casting according to the present invention relative to Jing Guo traditional heat treatment casting or basic not thermally treated casting
Especially there is improved intensity, and also there is improved intensity-elongation percentage ratio.
As the manufacturing method according to thermally treated, particularly as automotive chassis components the casting of the present invention, mainly
Applicable is permanent mo(u)ld casting method.Since the workpiece, component or component of high request need extraordinary mechanical performance, as system
Make method it is particularly suitable be gravity cast-in chills and low-pressure chill casting.
Especially by the casting method by pressure, such as low pressure-back pressure casting（CPC methods）, semisolid casting with
And such as high-pressure casting of the casting method of other compression power, cast forging（Cobapress）Or the low-pressure sand of cast molding device automation
Mold casting obtains preferable mechanical technology performance by good cast structure.Here back pressure-cast-in chills are particularly preferably
Method（CPC methods）.
In addition to already described advantage, according to the present invention, thermally treated casting also has the benefit that, since there is no conjunction
Golden component Cu and Zn and the corrosion resistance for significantly improving casting.This casting is also relatively cheap because use equally compared with
Expensive alloy additive, such as SE metals, it is possible to the common melt process of application and multi-cycle separation need not to be used for
Special consumption.
Specific implementation mode
Embodiment
In order to detect the mechanical performance of thermally treated casting, with low pressure-back pressure-cast-in chills method by alloy
AlSi3Mg0.5Cr0.7 casts turntable bearing and by the turntable bearing according to DIN50125:2009-07 manufactures tensile test bar.
Then solution annealing is carried out at 545 DEG C 0.5 to 6 hour and at the 200-220 DEG C of same heat aging for carrying out 0.5 to 6 hour
Reason.To mechanical performance tensile strength Rm, yield limit Rp0.2 and fracture elongation A5 is measured.DIN EN are used to this
ISO6842-1:2009-12.The value measured is shown in FIG. 1 in graphical form.
It is shown in figure, handles that 60 minutes following, particularly 30-59 divides by carrying out heat aging between 200 and 220 DEG C
Clock, it can be seen that fracture elongation significantly improves, and the raising of the fracture elongation is also along with the raising of tensile strength.At this
In, yield limit, which has, generally remains same high grade.
