Definitions
- the invention relates to the application of an aluminum-based intermediate alloy in metal processing, in particular to the application of an aluminum-zirconium-carbon intermediate alloy in the deformation processing of magnesium and magnesium alloys.
- magnesium and magnesium alloys are the lightest metal structural materials, they have low density, high specific strength and specific stiffness, good damping and shock absorption, good thermal conductivity, and electromagnetic
- the advantages of good shielding effect, excellent machining performance, stable dimensional dimensions, easy recycling, etc. make magnesium and magnesium alloys, especially deformed niobium alloys, have great potential applications in vehicles, engineering structural materials and electronics.
- the wrought magnesium alloy refers to a magnesium alloy which can be formed by a plastic forming method such as extrusion, rolling, or forging.
- the application of magnesium alloys, especially wrought magnesium alloys lags far behind steel and aluminum alloys. There is no such material in the field of metal materials. As with magnesium, there is such a big difference between its development potential and its actual application status.
- Magnesium is different from commonly used metals such as iron, copper and aluminum.
- Magnesium alloy is a hexagonal crystal structure with only three independent slip systems at room temperature. The alloy has poor plastic deformation ability, and its grain size has a great influence on mechanical properties.
- Magnesium alloy has a wide crystallization temperature range, low thermal conductivity, large body shrinkage, serious grain coarsening tendency, and defects such as shrinkage and thermal cracking during solidification; fine grains help to reduce shrinkage, Reducing the size of the second phase and improving the casting defects; the grain refinement of the magnesium alloy can shorten the diffusion distance required for solid solution of the intergranular phase and improve the heat treatment efficiency; in addition, the fine grains can also help to improve the resistance of the magnesium alloy. Corrosion properties and processability.
- grain refiner to refine the magnesium alloy melt is an important means to improve the overall performance of the magnesium alloy and improve the forming properties of the magnesium alloy.
- the strength of the magnesium alloy material can be improved, and the magnesium alloy material can be greatly improved.
- Plasticity and toughness make it possible to achieve large-scale plastic processing and low-cost industrialization of magnesium alloy materials.
- Zr The element that has a significant refinement effect on pure magnesium grains is Zr, which was discovered in 1937. Studies have shown that Zr can effectively inhibit the growth of magnesium alloy grains, thereby refining the grains. Zr can be used in pure Mg, Mg-Zn and Mg-RE systems; however, the solubility of Zr in liquid magnesium is very small. In the case of peritectic reaction, only 0.6 wt% Zr can be dissolved in the magnesium solution, and Zr and Al, Mn forms a stable compound and precipitates, and does not have the effect of refining crystal grains. Therefore, Zr cannot be added to the Mg-AI system and the Mg-Mn alloy. Mg-AI alloy is the most popular commercial magnesium alloy at present.
- the as-cast grains of Mg-AI alloy are relatively coarse, sometimes even coarse columnar crystals and fan-shaped crystals, which makes the ingot deformation process difficult, easy to crack, and the yield rate. Low, force The performance is low, and the rate of plastic deformation is very low, which seriously affects industrial production. Therefore, in order to achieve large-scale production, it is necessary to first solve the problem of as-cast grain refinement of magnesium alloy.
- the grain refining methods of the Mg-AI alloy mainly include a superheating method, a rare earth element addition method, and a carbonaceous growth method. Although the superheating method has a certain effect, the melt oxidation is more serious. The addition of the rare earth element method is not stable or desirable.
- the carbonaceous inoculation method has a wide range of raw materials and low operating temperature, and has become the most important grain refining method for Mg-AI alloys.
- the traditional carbon inoculation method uses MgC ⁇ 3 or C 2 CI 6 , etc.
- a large amount of dispersed AI 4 C 3 particles are formed in the melt, and AI 4 C 3 is a better heterogeneous crystal nucleus of the magnesium alloy, so that a large amount of dispersed AI 4 C 3 crystal nucleus refines the grain of the magnesium alloy.
- the refiner is added, the melt is easily boiled, so that it is rarely used in production.
- the general grain intermediate alloy has not been found in the magnesium alloy industry, and the range of use of various grain refining methods depends on the alloy system or alloy composition. Therefore, it is one of the keys to realize the industrialization of magnesium alloys by inventing a grain refiner which can be used in the solidification of magnesium and magnesium alloys and can effectively refine the as-cast grains and its application in continuous production.
