项目摘要
It is well known that magnetic properties such as the Curie temperature and the mean magnetic moment of ordered compounds have different values from those of disordered solutions. In consequence, the stability of the ordered phase is depressed (enhanced) due to the interaction between the chemical and magnetic ordering caused by the decrease (increase) of magnetic properties. In this project, a new thermodynamic model taking into account the interaction effect was developed by the collaboration with prof. Bo Sundman in the Royal Institute of Technology, Sweden. Model calculations to describe the phase stability of the b.c.c. and f.c.c. structures were performed taking into account the magnetic and the chemical ordering reactions and also the mutual interaction between them. Thermodynamic assessments of the Fe-X (X=A1, Ni and Co) systems were also carried out using two- or four-sublattice s-CEF, including the interaction effect. These calculations lead to the following conclusions.(1) The incomprehensible A2+B2 phase separation and tricritical point in the Fe-Al system originate in the depressed chemical and magnetic ordering energies caused by the mutual interaction.(2) The stability of both γ'-FeNi_3 (L1_2) and γ"-FeNi (L1_0) compounds is strongly enhanced by the additional magnetic energy due to the chemical ordering. The calculated phase diagram suggests that the γ"-FeNi (L1_0) phase is stable.(3) In the Fe-Co system, the stability of the B2 ordering arises mostly from the enhanced magnetic energy due to the chemical ordering.
众所周知,有序化合物的磁性质,如居里温度和平均磁矩,与无序溶液的值不同。结果,有序相的稳定性由于磁性的降低(增加)引起的化学有序和磁性有序之间的相互作用而被抑制(增强)。在这个项目中,一个新的热力学模型,考虑到相互作用的影响是由与教授Bo Sundman在皇家理工学院,瑞典合作开发。描述b.c.c.相稳定性的模型计算。和fcc考虑到磁性和化学有序反应以及它们之间的相互作用,进行结构化。热力学评估的Fe-X(X= Al,Ni和Co)系统也进行了使用两个或四个亚晶格的s-CEF,包括相互作用的影响。这些计算得出以下结论。(1)Fe-Al体系中A2+B2相分离和三临界点的产生是由于相互作用导致的化学有序能和磁有序能的降低。(2)γ ′-FeNi_3(L1_2)和γ"-FeNi(L1_0)化合物的稳定性都因化学有序化产生的额外磁能而大大增强。计算相图表明,γ"-FeNi(L1_0)相是稳定的。(3)在Fe-Co系统中,B2有序的稳定性主要来自于由于化学有序而增强的磁能。
