Synthesis of Bulk Nanostructured Al Alloys with Ultra-High Strength and Wear Resistance for Army Applications

摘要

Synthesis/processing of nanostructured (amorphous or ultra fine grained) materials was studied via various processing routes such as gas atomization, melt spinning, cryomilling, equal-channel angular pressing (ECAP) and conventional consolidation. Microstructures and mechanical properties of both the amorphous powders and consolidated bulk materials were characterized. The amorphous alloy of A185Ni10La5 (at.%) was fabricated in terms of melt-spun ribbons and particularly, gas-atomized powders.
