Fig. 5. Elemental distribution maps: a- nickel in the composite, b- carbon in the composite. As can be seen from the elements distribution maps, the light phase contains nickel and carbon. In addition, these elements are also contained in visually insoluble particles grouped at the ASP-50 particles boundaries. Nickel and carbon are evenly distributed, which allows us to assert that the introduced phase of nanotubes does not dissolve in Al at the selected temperature treatment of the material, under the conditions chosen by us for preparing CNTs for their introduction into the Al matrix. 3.2. Mechanical uniaxial stretching tests The mechanical properties of Al matrix composites were studied by uniaxial stretching. For comparative studies, the samples were also made of pure dispersed Al of the ASP 50 brand. As a result, deformation diagrams of synthesized Al matrix composites were obtained. The characteristics of samples of Al matrix composites containing different amounts of CNTs are shown in Fig. 6.
