Abstract

In recent years the problem of flight vehicles weight reduction becomes the most actual. At replacement of details from aluminum alloys on detail from high-strength magnesium alloys the weight economy about 20–25% can be reached. One of shortcomings of the deformed semi-finished products of high-strength magnesium alloys is anisotropy of their mechanical properties. It is conditionally possible to consider two types of anisotropy, in view of structural sign: – crystal (homogeneous) anisotropy; – heterogeneous (fibrous) anisotropy. For magnesium alloys both types of anisotropy are inherent. Anisotropy of mechanical properties can be reduced by applying the complicated scheme of deformation of material for receiving better structure and due to alloying magnesium, in particular, by rare earth metals (RE). The comparative analysis of results of microstructure research, phase structure research, mechanical properties and their anisotropy, investigation on example of high strength MA1
