Abstract

Foaming of gallium-based liquid metals improves their processability and - seemingly in contrast to processing of other metal foams - can be achieved through shear-mixing in air without addition of solid microparticles. Resolving this discrepancy, systematic processing-structure-property characterization demonstrates that many crumpled oxide particles are generated prior to air bubble accumulation.
