Synthesis of nanocomposites by mechanical alloying

Nanocomposites were synthesized by the solid-state powder processing technique of mechanical alloying in Al–Al2O3, TiAl–Ti5Si3, and MoSi2–Si3N4 systems. The mechanically alloyed powders were consolidated to full density by techniques such as vacuum hot pressing, hot isostatic pressing, and combinations of them. The as-milled powders as well as the consolidated compacts were characterized for their crystal structure features using X-ray...
