摘要
Resistivity of Mg63.5Zn34Y2.5 alloy including icosahedral quasicrystalline phase (I-phase) was measured. It shows that the quasicrystal alloy has a negative temperature coefficient of resistivity (TCR) before melting of I-phase. The TCR shows a reversible transition at similar to 1073 K during heating and cooling processes, involving evolution of icosahedral short-range orders (ISROs) inheriting from I-phase. The pre-existing ISROs act as templates in liquid and promote the nucleation of I-phase. (C) 2014 Elsevier B.V. All rights reserved.
