Дисперсионные соотношения для кристаллов твёрдых растворов со структурой CsCl

Дисперсионные соотношения для кристаллов твёрдых растворов со структурой CsCl

Abstract

Using a previously developed method, a dynamic model for the crystal structure of CsCl type is constructed. The model takes into account the interactions between the atoms of the first two coordination spheres. Based on experimental data on neutron scattering, calculations of the dispersion curves and elastic constants for crystal solid solutions of NiAl, ZnCu and FeAl are made.

На основе ранее разработанной методики построена динамическая модель для кристаллов, имеющих структуру типа CsCl, учитывающая взаимодействие между атомами на первых двух координационных сферах. С применением экспериментальных данных по нейтронному рассеянию сделаны расчёты дисперсионных кривых и упругих констант для кристаллов твёрдых растворов NiAl, ZnCu и FeAl.
