It is known that with increasing fineness of the structural components of the alloys the mechanical properties of the obtained products are increased. It is noted that a sufficiently large parts, components engineering products, produced by the foundry, due to inherent in this method advantages compared with other technologies for the manufacturing of parts, the most significant of which is the relative simplicity of the technology, however, allows to obtain a complex configuration details, which are almost impossible to produce by other methods, while ensuring the required technical documentation characteristics. These details, in particular, are cast parts, which are parts of the components, mechanisms and machinery transport machinery. However, in this industry, especially in aerospace engineering, widespread aluminum die casting alloys has received. In the manufacture of cast parts one of the main ways of improving quality is a modification, the essence of which consists in the introduction into the molten metal substances, which serve either as crystallization centers, or block the growth of emerging crystalline formations. To date, the "chopping" the possibilities of applying the means of modification, has reached its limit. And in recent years for this purpose there are more effective modifiers in the form of nanopowders of refractory high-strength chemical compounds (nitrides, carbides, oxides, borides, and others), the application of which leads to a significant enhancement of the mechanical properties of molded products. The paper presents examples of the application of nanpowders in the manufacture of aluminum alloys castings vehicles, as well as their use during welding, a process which is almost identical with the casting.
