Abstract

Controlling of a nucleation event is one of the important factors for preparing nanocrystalline materials via undercooled melt. We investigated nucleation behavior of an undercooled Pd₄₀Cu₃₀Ni₁₀P₂₀ melt, which exhibits exceptional high glass-forming ability and thermal stability using an in-situ high-resolution electron microscopy. As a result, generation and annihilation of a primary Pd₁₅P₂ phase with a diameter of about 15 nm was observed in the undercooled particle sample of about 25 nm. Not only the origin for high glass-forming ability of the alloy but also the control method of a nucleation in order to prepare a nano-crystalline material via undercooled melt are discussed.
