Abstract
It is extremely difficult to incorporate and disperse nanoparticles (NPs), especially for a high percentage, into metal matrix during solidification processing to achieve crucial property enhancement in metal matrix nanocomposites (MMNCs), mainly due to the strong tendency of NP aggregation. Thus, the significant property enhancement expected by the addition of a high percentage of NPs is rarely achieved in solidification processing of bulk MMNCs. Here we show that an unprecedented uniform distribution of 5 vol.% SiC NPs in Mgl8Sn alloy matrix is obtained by solidification processing. The resulting Mg18Sn matrix nanocomposites exhibits a very high microhardness value of 150 kg/mm2. The results reported in this work shed light on a potential pathway for production of ultrahigh performance metallic nanocomposites.
