NEUTRON STUDIES OF THE V-4Ti-4Cr ALLOY

DOI: 10.17804/2410-9908.2021.3.031-044

Competitive economic indicators for fast-neuron power reactors can be achieved with high coefficients of fuel burnout, which requires remarkable enhancement of radiation resistance of fuel pin claddings. Nowadays, low-activation vanadium alloys are projected as promising fuel cladding materials in view of their high radiation and thermal resistance in wide temperature and damage dose ranges. Neutron diffraction and small-angle neutron scattering are employed to study the microstructure of the V-4Ti-4Cr alloy subjected to irradiation with fast neutrons in the fluence range up to 1·1020 cm−2. Minor phases precipitated in the system are structurally characterized. The applicability and prospects of neutron diffraction methods in terms of studying the radiation behavior of this kind of alloys are shown.

НЕЙТРОНОГРАФИЧЕСКИЕ ИССЛЕДОВАНИЯ СПЛАВА V-4Ti-4Cr

Достижение конкурентных экономических показателей энергетических реакторов на быстрых нейтронах требует обеспечения высоких коэффициентов выгорания топлива, для чего необходимо существенное повышения радиационной стойкости оболочек топливных элементов. В качестве перспективных оболочечных материалов в настоящее время предлагаются малоактивируемые ванадиевые сплавы, обладающие повышенной радиационной и термической стойкостью в широких интервалах температур и доз радиационной повреждаемости. Методами нейтронной дифракции и малоуглового рассеяния нейтронов исследована микроструктура сплава V-4Ti-4Cr, облученного быстрыми нейтронами в диапазоне флюенсов до 1·1020 см–2. Определены характеристики минорных преципитатных фаз в системе. Показана возможность и перспективность использования нейтронографических методов для изучения радиационного поведения этой категории сплавов.
