Mechanics
of Amorphous and Nanoscale Metal Composites and Foam Structures
This IRG
on Mechanics of Amorphous and Nanoscale Metal Composites
and Foam Structures will focus on modeling and mechanical
characterization of i) monolithic amorphous metals
with improved combinations of strength, ductility, and toughness,
low cost, and processability, ii) composite materials having an amorphous
matrix combined with nanoscale or microscale dispersions of elastically "soft"
nano-scale crystalline dispersions having varying geometry and volume
 fractions, and varying degrees of elastic and plastic "mismatch" with
the amorphous matrix material, and iii) cellular amorphous
and or nano-crystalline structures with "open" or "closed" cell porosity
with cells (cell walls) having dimensions in the millimeter/micron
(micron/submicron) ranges.
This IRG builds
on the work of the previous IRG on Bulk
Metallic Glasses.
