摘要：

Coupled two-phase planar univariant eutectic growth occurs in Al-Cu-Ag alloys for different compositions and over a range of solidification velocities along the univariant eutectic reaction L --> alpha(Al) + theta(Al2Cu). The classical relationship lambda(2)nu = constant is obeyed. Two limits of stability are present: morphological stability and stability of the coupling. (C) 2004 Acta Materialia Inc.
