镍-铬合金中长程有序的发展具有很大的技术意义，但对这种转变的动力学和机制知之甚少。本研究采用计算和实验相结合的方法来阐明磷加速Ni-Cr合金化学计量比Ni 2Cr有序化速率的机制。制造一系列Ni-33% Cr-x%P样品（以原子百分比计），其中磷浓度为x = 0.000000，
The development of long range order in nickel-chromium alloys is of great technological interest but the kinetics and mechanisms of the transformation are poorly understood. The present research utilizes a combined computational and experimental approach to elucidate the mechanism by which phosphorus accelerates the ordering rate of stoichiometric Ni2Cr in Ni-Cr alloys. A series of Ni-33%Cr-x%P samples (in atomic percent) were fabricated with phosphorus concentrations, x =
