Experimental determination of microhardness at different chemical composition of materials of billets made of dispersion-hardened aluminum matrix alloys

The samples of experimental dispersion-hardened aluminum matrix alloys obtained by internal oxidation are studied. The influence of the content of different chemical elements in the structure of the material on the microhardness of billets made of hardened aluminum alloys is established.
