Description

HIGHLIGHTS 0% BEST DISCLOSURE The area of the invention The present invention is in the area of metallurgy, and more precisely - in the highest alloys of the past. 5 PREVIOUS LEVEL OF TECHNOLOGY

The current period of various differences in technology has strengthened the need for the creation of new competitive materials that are more comfortable.

The most attractive of the metallic materials of the United States with this view are magnesium and alloys on its basis. The existing methods for the refinement of magnesium alloys are mainly based on alloying. The alloying of magnesium alloys is carried out by metals, which are processed with magnesium and metal. Intermetallides are a refinement of phase 15 in any of the well-known high-strength magnesium alloys. Achieved by this level of standard (temporary equipment) is approximately 25 PSa.

Ζг _and others.

However, the achievable basic char- acteristics in these 25 alloys is already not sufficient, due to increased purchases of parts and accessories.

Studies have shown that a further increase in the direct availability of magnesium and the grinding of magnesium particles and the grinding of particles of an intrinsic magnifying phase.

Of the part, the magnesium alloy ( ^Pβ , Α, 4997622) with the value of the temporary resistance of 290 0 Pa, and in some cases χ 330 Μ Pa, having the following weight composition: ΑΙ - 2-11, 0 ^Μ ^η , is ^known 0.6, Ca - 35 0-7%. The average grain size is 3 μm, a homogenous matrix, enlarged (aromatic) integrated compounds with particle sizes less than 1 μm, isolated on the grain boundary. However, such crushing of grain and the cultivation of an interme- diate is possible only for the use of special types of processing. In this case, it is a quick installation method requiring the use of sophisticated equipment, which has 5 low productivity. In other words, the isolation of intermetallic compounds at the borders of the world separates the low characteristics of the plasticity of the alloy.

It is advisable that in a patented zinc alloy, soda should complain no more than 6, manganese - no more than 3%, cirrus - no more than 4%, and Russia - no more than 4. 30 It is expedient in the same alloy to limit the content of rare-earth metals to 2.5%.

In the case of inventions, use the connection of nitrogen and acid with any of the above elements in the form of nitrides and oxides. 35 In general, the described alloy has increased, excellent performance, high flexibility and good working quality. - 3 - SUMMARY OF THE INVENTION is as follows. Introduction to magnesium alloy is a supplement in the form of compounds of nitrogen and oxygen with magnesium or any alloying compound that ensures the conversion of high-quality particles to minerals.

5 related to the matrix. For this part of the machine, being the center of installation, it is possible to produce a small-sized alloy structure, and, in addition, is an important part of the process. This separates the alloy from the alloy and maintains a high level of plasticity.

10 parts that allow you to use such an alloy in the most difficult loaded parts and assemblies of different products. It is necessary to indicate that the content of zinc in the alloy does not have to increase 6%, since it increases the incidence of damage to the product

15 is the fame of the fame.

With an increase in manganese content in the alloy more than 3% of the gravel alloy grows and, in its turn, the production of manganese is not neglected, it is not forgotten.

25 With an increase in the content of the alloy in the alloy more than 4%, the grain alloy will grow and its plasticity will decrease.

The content of underground metals in fusion does not have to increase 2.5%, since a further increase in it causes the formation of a continuous chain of excluded eutectic

30 grains, which also reduces the plasticity of the alloy.

Of the compounds of nitrogen and acid with any of the elements used in the alloy, in addition to the beneficial use of nitrates and oxides, as well as the more active in the fusion.

35 Bearing in mind that the proposed alloy has the following properties - a temporary increase of not less than 400 Μ, but an increase of ^ 6%, it can be _ - The best option for carrying out the invention. The above studies have shown an optimal composition of alloying elements and addi- tives in magnesium alloys Magnesium alloys with typical suppliers of alloying elements selected from the group of metals were produced: ΑΙ, ^Ζ , Μ ^η , Ζг, ЬЬ. and ΡΡΜ and the addition of nitrogen and oxygen compounds with these metals and magnets, the resulting chemical system is separated and the batteries are separated (10 The results of the research are presented in Table I.
