摘要

具有优异性能的材料在技术应用中不可或缺。在液态铅金属冷却核反应堆的设计中，具有高强度、耐热、耐腐蚀性能的钢材是不可或缺的。铁镍合金钢是其中一种需要研究以获得优异性能的钢材。本研究采用模拟分子动力学的计算方法研究了铁镍钢成分的影响。使用 CNA（共邻分析）方法分析了能在液态铅反应堆冷却剂中工作的镍铁合金钢的确切成分。分子动力学模拟使用 MOLDY 程序，而 CNA 值的计算则使用OVITO 程序。从模拟结果可以看出，铁和镍成分的变化能够产生最稳定的铁镍合金钢，不受液态铅金属腐蚀的影响。

FeNi steel alloys under effect of molten lead liquid at high temperature 750â„ƒ: A molecular dynamics simulation study

Materials that have superior properties are indispensable for technological applications. Steel that has strong, heat- resistant, corrosion-resistant properties is indispensable for application in the design of liquid lead metal-cooled nuclear reactors. One of the steels that need to be studied for superior properties is FeNi alloy steel. In this study, the influence of FeNi steel composition was studied using computational methods of simulating molecular dynamics. The exact composition of FeNi steel to be able to work in liquid lead reactor coolant was analyzed using the CNA (common neighbor analysis) method. Molecular dynamics simulation uses the MOLDY program while the calculation of CNA values uses the OVITO program. From the simulation results, it can be known the effectiveness of variations in Fe and Ni composition that are able to produce the most stable FeNi alloy steel from the influence of liquid lead metal corrosion.
