Abstract
The invention relates to magnesium-based alloys, in particular to the composition of magnesium alloys and methods for the production thereof, said alloys being widely used for the automobile industry. The aim of said invention is to produce an alloy having more fine grain structure which improves the mechanical properties thereof. The invention makes it possible to produce the alloy provided with mechanical properties suitable for pressure-die casting. The inventive magnesium-based alloy contains aluminium, zinc, manganese, silicium and calcium. The novelty of the alloy lies in that the ingredients thereof are contained at the following element ratio in mass %: 8.5-9.5 of aluminium 0.45-0.90 of zinc 0.1-0.40 of manganese 0.21-0.50 of silicium 0.05-0.10 of calcium, magnesium being the rest.

Calcium is the most economical element for the magnesium alloy and improves the high-temperature stability and the efficiency of the use of magnesium alloys. However, when calcium is included in the alloy on the basis of magnesium-aluminum, the fluidity of the alloy significantly deteriorates so that the alloy is no longer subjected to pressure. Calcium in large quantities causes damage to household goods and casting. Therefore, the calcium content in the amount of 0.05-0.10%) weight. Allows you to reduce the probability of excreting Μ§ 2 8ι into large compartments that are faster 5 reduce the plasticity of the alloy and not reach the required properties of magnesium alloy.
