项目摘要
The present study dealt with molecular dynamics (MD)simulations to analyze the atomic-scale structure of metallic glasses and the development of a new bulk metallic glass (BMG). A MD simulation model by referring to a plastic crystal was performed where the plastic crystal is known as an intermediate phase between a liquid and solid phase in a class of molecular materials. Simulation results revealed that BMGs possess critically-percolated, cluster-packed structure. Furthermore, considerations of the simulation results make it possible to produce a high-entropy bulk metallic glass with a critical diameter of 10 mm in a Pd_20Pt_20Cu_20Ni_20P_20 alloy as a new type of bulk metallic glass.
本研究涉及分子动力学(MD)模拟,以分析金属玻璃的原子尺度结构和新型块体金属玻璃(BMG)的开发。参考塑性晶体进行MD模拟模型,其中塑性晶体被称为一类分子材料中液相和固相之间的中间相。模拟结果表明,BMG 具有临界渗透、簇堆积的结构。此外,考虑模拟结果,可以在Pd_20Pt_20Cu_20Ni_20P_20合金中生产临界直径为10 mm的高熵块体金属玻璃,作为一种新型块体金属玻璃。
