Nanostructuring of Dispersion-Reinforced Aluminum-Matrix Composite Materials

摘要

We studied the effect of reinforcing phases introduced into the melt ex situ and formed directly in situ during mechanical activation of powders or mechanical mixing in the melt on the structure and mechanical and tribological properties of aluminum-matrix cast and aluminum-powder composites. Intermetallic inclusions, Al_2O_3, TiC, SiC, and refractory nanoscale particles served as reinforcing agents.
