| Abstract Scope |
Radiation-induced embrittlement is an important technical challenge limiting the design and operation of advanced nuclear energy systems. Over the past few decades, tremendous efforts have been made to understand the microstructural construction that can mitigate such deterioration of nuclear materials, focusing primarily on using crystallographic interfaces, such as phase or grain boundaries. These interfaces are known to serve as effective sink sites for point defects generated by irradiation. In this presentation, I will discuss results from our recent studies on the effects of proton irradiation on the interfacial plasticity in nano-twinned copper, with a particular emphasis on perfectly coherent twin boundaries. By performing in-situ nano-tension experiments, we demonstrate that these interfaces have the capability to absorb and heal radiation damage while maintaining their role in facilitating plasticity |
