摘要：
The structural state of a Ti50Ni47Fe3 single crystal irradiated with fast neutrons (F = 2.5 × 1020 cm−2) at a temperature of 340 K was studied using thermal neutron diffraction. The alloy of this chemical composition was chosen in searching for a radiation-resistant shape memory material. It is established that this alloy retains its crystalline state after irradiation, whereas the Ti49Ni51 crystal studied previously is completely amorphized after similar irradiation. A detailed analysis of the structural state of the irradiated ternary alloy allowed us to discover the main physical causes of its radiation resistance.
