Description
Technical field
The invention belongs to non-ferrous metal structural material and field of metallurgy, and in particular to a kind of high intensity Mg-Sn-Ca-Ag systems
Magnesium alloy and preparation method thereof.
Background technology
Magnesium alloy is gradually paid close attention to by the mankind as most light one of structural material, with society fast development,
Advantage is gradually found, and is come into operation.That the biggest advantage is to density is small for magnesium alloy, and with higher than strong
Degree and specific stiffness；In addition functionally, magnesium alloy has higher thermal conductivity, damping shock absorption, electromagnetic wave shielding；It is opened from market
It sends and says, magnesium occupies the third position of metal in earth rich reserves, while having the characteristics that easy to process and easy recycling, this makes
Obtaining magnesium alloy has higher cost performance, is conducive to its application in market.Limit the principal element of magnesium alloy development and application
It is the failure to well solve mechanical behavior under high temperature, corrosion resistance and the moulding processing performance of magnesium alloy.In research field, pass through
Constantly improve material alloys elemental composition, manufacturing process and heat treatment process to improve the comprehensive performance of magnesium alloy.In recent years,
Through forming more ripe Mg-Al systems, Mg-Zn systems, Mg-Re systems high-strength magnesium alloy, but the height of Mg-Al systems and Mg-Zn systems alloy
Warm nature can be unsatisfactory, and when temperature is increased to 150 DEG C, intensity declines rapidly, and the cost of Mg-Re systems alloy is relatively high, very
Hardly possible realizes industrialization.
Mg-Sn alloys gradually attract attention, and main cause is Mg therein2Sn hardening constituent fusing points reach 770.5 DEG C；Separately
Outside, solid solubility of the Sn in Mg is preferable, and precipitating reinforcing effect is relatively good, and solubility 14.48% at 561 DEG C, 200 DEG C are reduced to
0.45%, solid solution aging reinforcing works well.But the aspect for needing to continue to improve there are still two：First, it is thick that phase constitution is precipitated
Greatly, nonuniform organization causes the strong plasticity of alloy poor；Second, as cast condition Mg-Sn alloys precipitated phase is in mainly net distribution in crystalline substance
Boundary and dendrite wall, the operating temperature of eutectic state is relatively low, and lacks transgranular reinforcing effect, so also further increase
Space.Many researchs promote timeliness by adding the trace alloying elements such as alloy element Zn, Ag, Na, Zr, Mn at present, improve
Alloy comprehensive performance.Granted patent CN 102358929 discloses Ag has the apparent work for promoting timeliness to Mg-Sn alloy groups
With.On the basis of Mg-Sn bianry alloys, the Mg-Sn-Ca ternary alloy systems plate that research has gradually developed, but is precipitated recently
Strip CaMgSn stable dimensions are coarseer, its development and application is made to be restricted.Patent CN 101985713, CN
101440438, CN 101440441 individually disclose the work by adding the elements such as Ce, Y, Sr to play apparent refinement CaMgSn phases
With improving the performance of Mg-Sn-Ca systems magnesium alloy.To improve the performance of Mg-Sn systems alloy, the present invention, which proposes, utilizes Ag energy
It refines CaMgSn phases and effectively facilitates Mg2The Mg-Sn-Ca-Ag series high strengths magnesium alloy and its system of the dual invigoration effect of Sn phases
Preparation Method makes the intensity of alloy significantly improve.
Invention content
The present invention to the refining effect of the CaMgSn phases in Mg-Sn-Ca alloys and promotes Mg using Ag2Generation is precipitated in Sn
A kind of invigoration effect, it is proposed that Mg-Sn-Ca-Ag series high strengths magnesium alloy and preparation method thereof.CaMgSn phases are refined by Ag
Effect makes alloy have higher intensity, overcomes that plasticity caused by CaMgSn phase is coarse in Mg-Sn-Ca alloys is poor to ask
Topic.Using solid solution+aging thermal treating process, Ag has been given full play to Mg2The facilitation of Sn precipitation strengths, forms disperse
Mg2Sn precipitated phases make the intensity of alloy be further enhanced, and maximum hardness reaches 81.7HV.
The ingredient and mass percent of Mg-Sn-Ca-Ag series high strengths magnesium alloy proposed by the present invention be：
Tin（Sn）：4.0-10.0%；Calcium（Ca）：0.5-3%；Silver（Ag）：0.5-2.5%；Remaining is magnesium（Mg）, it is desirable that Ca/Sn

Percentage carries out dispensing：Tin（Sn）：4.0-10.0%；Calcium（Ca）：0.5-3%；Silver（Ag）：0.5-2.5%；Remaining is magnesium（Mg）.Gold
Belong to Mg, for the purity of Sn, Ag more than 99.9%, melting protective atmosphere is 99%CO2+1%SF6Mixed gas, concrete technology are：
（1）Alloy is smelted using crucible for smelting stove, after the temperature of smelting furnace is raised to 400-500 DEG C first, is led into stove
Enter protective gas 4-6 minutes, then ready pure magnesium metal derby is put into smelting furnace, then furnace temperature is raised to 700 DEG C -720
DEG C, the slag after the fusing of magnesium metal derby above removal liquid melts；
（2）Mg-Ca intermediate alloys are added in completion after removing slag, then furnace temperature is raised to 740 DEG C -760 DEG C and keeps the temperature 20 minutes.It waits for
After the completion of the dissolving of Mg-Ca intermediate alloys, furnace temperature is dropped to 700 DEG C -720 DEG C, then Ag, Sn metal is successively added, while stirring liquid
Then state melt carries out deslagging refining；
（3）It is kept the temperature at 700 DEG C after the completion of second of slagging-off, keeps the temperature 10-15min, liquid melts are then molded into metal
In mold, natural cooling obtains cast alloy, and metal die requires the preheating by 200 DEG C -250 DEG C；
Step 2：Homogenization and solution treatment
Alloy blank is kept the temperature 16 hours at 390-400 DEG C and carries out Homogenization Treatments, carries out water cooling, solution treatment is will to close
Gold at 450 DEG C -470 DEG C, keep the temperature 2-6 hour, then alloy is cooled down in water, it is all be heat-treated under protective atmosphere into
Row；
Step 3：Ageing treatment
Under the conditions of atmosphere protection, it is small that the alloy after solution treatment is carried out at a temperature of 160 DEG C -230 DEG C to 110-170
When ageing treatment.
The preparation method of Mg-Sn-Ca-Ag series high strengths magnesium alloy proposed by the present invention, sets according to the optimization of alloying component
Meter is theoretical with alloy strengthening, so that the heat-resisting phases of the CaMgSn of Mg-Sn-Ca alloys is refined by the common addition of Ca, Ag, Ag pairs
Mg2Significant facilitation is played in the precipitation of Sn phases, can be efficiently used in alloy by solid solution aging technique proposed by the present invention
Mg2The disperse educt of Sn improves the room temperature intensity and elevated temperature strength of Mg-Sn alloys, and Ag can shorten arrival age-hardening peak value
Time, the hardness of alloy is up to 81.7HV after solid-solution and aging heat treatment.
