摘要/Abstract

摘要： The nanocrystallization behaviour of Zr$_{70}$Cu$_{20}$Ni$_{10}$ metallic glass during isothermal annealing is studied by employing a Monte Carlo simulation incorporating with a modified Ising model and a $Q$-state Potts model. Based on the simulated microstructure and differential scanning calorimetry curves, we find that the low crystal-amorphous interface energy of Ni plays an important role in the nanocrystallization of primary Zr$_{2}$Ni. It is found that when $T
