Abstract:
1. A solidified foam bulk amorphous alloy structure comprising a foam structure of a bulk solidifying amorphous alloy having a critical cooling rate at about 500 K/sec or less wherein a continuous piece of the bulk solidifying amorphous alloy is connected through a pore structure comprising a plurality of pores and wherein the size of each pore is from 1 micron to up to 5.0 mm in size and the volume fraction of the plurality of pores is from 10% to up to 95% or more such that the solidified foam bulk amorphous alloy structure is superior to the monolithic solid form of the base bulk solidifying amorphous alloy in at least one of the characteristics selected from the group consisting of specific modulus, specific strength, elastic strain limit, energy absorption, fracture toughness, and crack propagation resistance.
