Abstract

In this paper, based on the results of experimental studies of the temperature dependences of magnetization of Ni51-xMn33.4In15.6Vx (x = 0; 0.1; 0.3; 0.5; 1 at.%) and Ni46Mn41In13 Heusler alloys in weak and strong magnetic fields, a phenomenological model is proposed that explains the features of phase transitions, namely: a decrease in the temperature of the first-order metamagnetostructural martensitic phase transition under the influence of a magnetic field and the degree of alloying of the alloy. The results of accurate analytical calculations and numerical modeling are presented and compared.

  • Heusler alloys
  • martensitic transformation
  • phase magnetizations
  • metamagnetostructural phase transition
  • interaction of phase transitions

Термодинамическая модель для описания особенностей фазовых переходов в сплавах Гейслера системы Ni-Mn-In, легированных ванадием

В работе на основе результатов экспериментальных исследований зависимостей намагниченности от температуры сплавов Гейслера Ni51-xMn33,4In15,6Vx (x = 0; 0,1; 0,3; 0,5; 1 ат.%) и Ni46Mn41In13 в слабых и сильных магнитных полях, предложена феноменологическая модель, объясняющая особенности фазовых переходов, а именно: снижение под влиянием магнитного поля и степени легирования сплава температуры метамагнитоструктурного мартенситного фазового перехода 1-го рода. Приводятся и сравниваются результаты точных аналитических расчетов и численного моделирования.
