摘要: Liquids of silver-copper alloys with near eutectic compositions embedded in a copper matrix were undercooled. The structural and microstructural investigations these solidified from undercooled temperature indicated the absence both reaction diffusionless transformation below equal free energy curve (T0). Instead liquid maintained local equilibrium dendrites continuously until it intersected extended solidus silver rich solid solution.
