“…In addition, the effect of anisotropy on the deformation process has been found to have a nonlinear symmetry at low temperatures [51]. Morse interaction potential is widely used in the process of studying defects and deformation of metals and alloys [52,53]. Several studies revealed the Cu-Au alloy is a binary alloy that survives temperature-induced transformation and is stable long term, with a super-cohesive structure [54][55][56][57][58].…”

In this study, molecular dynamics simulations have been used to study the influencing factors, such as the time of each heating step, temperature, and annealing time, on the structure and crystallization process of Cu–Au alloy. The results show that when the temperature increased, the crystallization process decreased, and the structure gradually turns to the liquid state, and vice versa. When increasing the time of each heating step and the annealing time, the crystallization process increased, then increased the most at the glass temperature, Tg = 550 K. During the phase transition, link length (r), total energy (Etot), size (l), number of FCC, HCP, and Amor structural units have a significant change. The obtained results of Cu-Au alloy can serve as a basis for future experimental studies.

The stress-time relation and energy-time relation for different nickel nanowires were studied under uniaxial deformation of tension. The stress-strain diagrams were obtained by the method of molecular dynamics (MD). Simulation of the tensile specimens of these Ni nanowires showed a rapid increase in stress up to a maximum followed by a gradual drop to zero when the specimen fails by ductile fracture. The stress-strain curve under extension loading and plastic deformation was studied. The maximum stress and strain at maximum stress had the same value for different Ni nanowires.

“…В литературе представлено большое количество работ по теории упорядочивающихся сплавов и моделированию фазовых диаграмм, где обсуждаются, типы и кинетика фазовых переходов порядок-беспорядок, описываются структурные и энергетические характеристики дефектов, приводится расчет стехиометрии и температур фазовых переходов [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. В работах [7,8] была предложена двумерная модель, позволяющая изучать кинетику упорядочения сплавов в модели жесткой кристаллической решетки. Данная модель была обобщена на случай трехмерных решеток и использована при изучении структурно-фазовых превращений ряда сплавов стехиометрических составов [9][10][11][12][13], в том числе, с учетом влияния антифазных границ [10].…”

Предлагается алгоритм построения термических кривых охлаждения и кинетики упорядочения при монотонном понижении температуры сплавов стехиометрических составов в модели жесткой кристаллической решетки и парных межатомных взаимодействий. Применение алгоритма иллюстрируется на примере квадратной решетки при учете межатомных взаимодействий в первых двух координационных сферах для сплавов состава AB, A 3 B и A 3 B 5. Предложенная модель позволяет рассчитывать отдельные области фазовых диаграмм состояния бинарных сплавов. Ключевые слова: кристаллическая решетка, бинарный сплав, упорядоченный сплав, фазовая диаграмма состояния. An algorithm of calculation of thermal cooling curves and ordering kinetics during monotonous decrease of temperature of a stoichiometric binary alloy is offered. The algorithm is based on the assumptions of rigid crystal lattice and pairwise interatomic potentials. As an example of application of this algorithm the AB, A3B, and A3B5 alloys based of the square lattice are considered taking into account atomic interactions up to the second coordination sphere. The developed algorithm can be used for modeling certain elements of binary alloy phase diagrams.
