Abstract

When a eutectic alloy melt is undercooled well below its liquidus T1, liquid state phase separation occurs. The liquid morphologies can be frozen by subsequent crystallization. It was found that for Pd82Si18 when rapid quenching is also employed, ore of the phase-separated liquids after solidification is amorphous. The undercooled specimen is in bulk form with a diameter of ∼ 5 mm.
