Synthesis of bulk amorphous composites with three amorphous phases by consolidation of milled amorphous powders

Bulk amorphous composite with three amorphous phases was fabricated by consolidation of milled amorphous composite powders. The amorphous composite powder was synthesized by a controlled milling process using the Cu-based amorphous powder blended with 30 vol% Zr-based amorphous powders. The milled composite powders show a layered structure with three amorphous phases, which is formed as a result of mechanical mixing by milling. By spark plasma sintering of milled amorphous powders in the supercooled liquid region, a fully dense bulk amorphous composite was successfully synthesized.
