High Performance Mg6Zn Nanocomposites Fabricated through Friction Stir Processing
Mg-based metal matrix nanocomposites (MMNCs) are expected to provide significant enhancement of properties by introducing thermally stable ceramic nanoparticles into the metal matrix. However, it is extremely difficult to achieve a uniform distribution of nanoparticles in the magnesium matrix for the predicted significant property enhancement. In this study an unprecedented uniform distribution and dispersion of 6 vol.% SiC nanoparticles in Mg6Zn matrix was obtained through a novel scalable processing method that combines semi-solid mechanical mixing and solid-state friction stir processing. The resulting Mg6Zn nanocomposites exhibit tremendous hardness and strength enhancement. The results provide a viable pathway for the development and production of high performance Mg-based nanocomposites for numerous applications.
