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.

空气介导的剪切混合过程中氧化介导的镓泡沫的产生和稳定机理。

镓基液态金属的发泡提高了它们的可加工性，而且与其他金属泡沫的加工相比，似乎可以通过在空气中进行剪切混合而无需添加固体微粒来实现。通过解决这一差异，系统的处理，结构，性能表征证明，在气泡积聚之前会产生许多皱缩的氧化物颗粒。
