Coupled growth of Al-Al sub(2)Cu eutectics in Al-Cu-Ag alloys

Coupled eutectic growth of Al and Al sub(2)Cu was investigated in univariant Al-Cu-Ag alloys during solidification with planar and cellular morphology. Experiments reveal the dynamic selection of small spacings, below the minimum undercooling spacing and show that distinct morphological features per...

Zusammenfassung:Coupled eutectic growth of Al and Al sub(2)Cu was investigated in univariant Al-Cu-Ag alloys during solidification with planar and cellular morphology. Experiments reveal the dynamic selection of small spacings, below the minimum undercooling spacing and show that distinct morphological features pertain to nearly isotropic or anisotropic Al-Al sub(2)Cu interfaces
