Investigation of the structure and mechanical properties of castings of alloy AlSi7Mg, cast irons GG15 and GG25 and steel GX120Mn12, modified by nanosized powders

Autor: Roumen Petrov, Valentin Manolov, R. Lazarova, Pavel Kuzmanov, Rosica Dimitrova, A. N. Cherepanov, Saho Popov

Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part N: Journal of Nanoengineering and Nanosystems. 228:11-18

The influence of nanopowders on the structure and mechanical properties was investigated in castings of aluminium alloy AlSi7Mg, grey cast irons GG15 and GG25 and steel GX120Mn12. Mixtures of SiC, TiCN and Y2O3 nanopowders were used. These mixtures o
