Radiation Resistance of Ultrafine Grained Stainless Steels
Project Status: 3 Approved without Funding
Duration in months: 36 months
Objective
The proposed research focuses on austenitic stainless steels (301/304/316SS), operated in the core of nuclear reactors under an intensive impact of neutron flux, temperature gradients and stresses. The project examines radiation damage effects on ultrafine grain structures (up to 5im) of reactor steels and carries out comparison analysis with similar effects to conventional microstructure. The primary aim of the research is to clarify the mechanisms describing the radiation-induced hardening and embrittlement (i.e., reduction in the ductility characteristics) by carrying out neutron irradiation in the WWR-K reactor (Almaty) of traditional and fine-grained austenitic steels. The subsequent investigations will be followed by performing comparative complex materials science studies and data analysis (mechanical testing at different temperatures, corrosion testing, magnetometry, microhardness and electron microscopy).
