Abstract
Demonstrating the cooling rate effect on the solidification path is a massive challenge. In this paper, the atomic structure of the Pd40Ni40P20 melt was statistically “snapped” at different temperatures with two different cooling rates. The structure evolution was analyzed with in situ high-energy X-ray diffraction method and Reverse Monte Carlo simulation. It indicates that the presence of Liquid-Liquid Phase Transition (LLPT) makes the melt more inclined to form crystal but the higher cooling rate leads to an insufficient transition retaining more icosahedral-like clusters. This work provides dynamic guidance for understanding the competition between crystallization and vitrification.
期刊介绍：
Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
