Microstructure of aluminum-matrix cast disperse-filled composite material obtained by internal oxidation
In work the developed technology of creation of the disperse strengthened material on the basis of internal oxidation of aluminum fusion at interaction with oxygen-nitrogen mix. Results of the microstructural analysis of the received samples, including 3D structure of breaks of samples after test on shock are presented by viscosity. During the carried-out work was it is almost confirmed perhaps creations of the disperse strengthened material on the basis of aluminum with an introduction phase size from 5 µm to 2 mm and extent of saturation to 80 % It allows to change mechanical properties of the received product substantially. It is shown that due to change of the technological mode of receiving material it is possible to achieve a considerable variation of the size and the maintenance of the strengthening phase. It allows to change mechanical properties of the received product substantially.
