| Abstract Scope |
There is a worldwide need of nuclear energy due to the increase in the world’s population and the desire to reduce greenhouse gasses from burning of fossil fuels. However, nuclear energy systems operate under high temperatures and stresses, chemically corrosive environments, and high neutron fluxes. Engineered ferritic alloys are one of the best materials for high temperature and extreme radiation environments. Moreover, new material system of refractory high entropy alloys (RHEAs) have demonstrated great promise. In this study, thermal stability and radiation resistance of nanostructured ferritic alloy (NFA), 14YWT, produced by powder metallurgy methods and TiZrHfNbTa RHEAs produced by vacuum arc melting and additive manufacturing techniques have been investigated. Recently, we have shown that NFAs and RHEAs are extremely stable up to >1000 ⁰C and they show almost zero swelling under high dose irradiation. |
