One, it tests：
Entire experimental stage is divided into two stages：
First stage：By the formula of the Mg elements of different content in embodiment 1 to embodiment 7, casting forging and stamping are carried out, continuous casting squeezes
Pressure, molding；
Second stage：Selected characteristic ingredient carries out microstructure research, and inquires into the strengthening process of precipitated phase.
1, test material and composition design, use equipment
This experiment is mainly the ADC12 aluminium alloys using Shenzhen Li Chang（Hereinafter referred to as control group 1）, optimize Mg members on its basis
Cellulose content detects the ingredient of each alloying element in the ADC12 of Shenzhen Li Chang by spectroanalysis instrument first（Such as the following table 1）, experiment
Equipment master has medium frequency induction melting furnace, electron microscope, Vickers, universal testing machine etc..
2, process is tested
Using obtained alloy is formulated in control group 1 and embodiment 1 to embodiment 7, be added at 760 DEG C grain refiner and
Alterant keeps the temperature and takes off Slag treatment after 10min alloy is pressed into crucible bottom with bell jar again, ensures whole meltings, then in swage
Middle casting forms billet, carries out ageing treatment, 550 DEG C of aging temp after solution heat treatment again（8H）+200℃（2H）, then take
Sample detects control group 1 and embodiment 1 to the tensile strength of the aluminium alloy of embodiment 7, hardness, microscopic structure and power spectrum respectively
Analysis.Production process charts are shown in Fig. 1.
3, following table 1 is each element content of embodiment 1 to 7, control group 1 and control group 2
4, test results and analysis
（1）Crystalline phase fabric analysis
Label in Fig. 2 and Fig. 3 is to the figure for scheming e, is the crystalline phase group of control group 2 and embodiment 3 to the sample of embodiment 6
Knit analysis chart；
Analysis：
Mainly Mg alloying elements are analyzed, by as shown, the crystalline phase tissue of different content Mg alloys is different, wherein a is pair
It is organized as black matrix to be not added with Mg elements according to the crystalline phase organization chart of the sample of group 2 and flocks together, the tree connected on a small quantity
Dendritic, energy spectrum analysis essential element contains Al, Si, Cu, Fe etc..When alloy graining, the binary eutectic of crystalline A l and Si first, most
After become Al, Si, Cu ternary crystallization.It is crystalline phase of the embodiment 3 to 6 sample of embodiment such as b, c, d, e after adding Mg elements
The content of organization chart, Mg elements is in increased trend, as Mg contents increase, except white bars block increases, and dendroid eutectic
Si aggregations face tapers into, and when the addition of Mg is below 1.0%, the increase of Mg therewith contributes to thin common reciever, and can overcome
The segregation of common reciever, the Mg of formation2The more intersections for being distributed in common reciever and α-Al of Si, when Mg contents reach 1.1%
（See the d in Fig. 3）, matrix Al and eutectic Si distributing equilibriums.
（2）Tensile strength is analyzed
Fig. 4 is tensile strength analysis chart.
Fig. 4 is influence of the Mg contents to strength of alloy.
By analyzing strength of alloy after improvement, such as Fig. 4, strength of alloy is increased with the increase of Mg constituent contents,
When Mg constituent contents reach 1.0%, tensile strength maximum value 270Mpa, being then further added by intensity will decline.In control group 1, Mg
Constituent content is 0.1%, and tensile strength is about 253 Mpa, and in control group 2, Mg constituent contents are 0, and tensile strength is big
About 250 Mpa.The Mg constituent contents of embodiment 1 to embodiment 7 are in increasing trend, therefore, the conjunction of embodiment 1 to embodiment 4
Golden tensile strength year g constituent contents increase and increase, when reaching Mg constituent contents and reaching 1.0%, tensile strength is up to maximum
Value, then, tensile strength is on a declining curve.
（3）Hardness analysis
Fig. 5 is hardness analysis figure.
Fig. 5 is influence of the Mg contents to alloy rigidity.
By to its hardness analysis it is found that alloy rigidity value is reinforced with Mg contents by increasing, when Mg contents are 1.0%, firmly
Degree is up to 120HB, and subsequent Mg contents continue growing, and hardness is then begun to decline.
（4）The comparative analysis of other every mechanical properties
1, Mg elements are added to the invigoration effect of aluminium alloy it is obvious that when Mg constituent contents are less than 1.0% in alloy in Mg elements
The diffusion that can promote inner alloy element helps refine Si phases, to greatly improve its mechanical property, and ADC12 alloys
As cast condition and T6 states intensity are improved with the increase of Mg constituent contents, and when magnesium element content is more than 1.0%, the intensity of alloy
Decline.The strengthening mechanism of the alloy is mainly to form suitable Mg2Si hardening constituents and refining eutectic silicon mutually not segregation.
2, Mg elements can inhibit the illeffects of Fe phases, reduce casting defect.
