These Fe-Cr based alloys, particularly those with around 10 at% Cr, offer excellent resistance to swelling and corrosion under irradiation, and exhibit minimal radiation-induced ductile to brittle transition temperature (DBTT) shifts. However, the extreme environment within a fusion reactor, characterized by intense neutron fluxes and high temperatures, presents significant challenges to these materials.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

PALS enables to detect and to analyze microstructural changes and defects in the materials at an atomic level<\/strong>, providing unparalleled insights into radiation-induced damage mechanisms. By simulating the harsh conditions of a fusion reactor through controlled ion irradiation experiments conducted at the Ion Beam Center at HZDR, they could closely examine how these materials behave and evolve.<\/p>

The data gathered from these experiments are invaluable, not only for enhancing our understanding of radiation effects<\/strong> but also for developing predictive models<\/strong> that will guide the creation of more resilient, neutron-resistant materials. These innovations are crucial for the success of future fusion reactors, which will rely on materials that can withstand prolonged exposure to radiation while maintaining their structural integrity.<\/p>

Moreover, RAFM steels offer significant environmental benefits<\/strong>, aligning with the principles of the circular economy. These materials can be recycled<\/em> and reused<\/em> after a certain period, minimizing radioactive waste and reducing the overall environmental impact of fusion energy technology.<\/p>

Special thanks to Maik Butterling, Maciej Oskar Liedke, and Eric Hirschmann for their invaluable support during the beamtime and the ongoing analysis of this promising data as well as to Miguel Sequeira for his support during the materials irradiation experiments.\u00a0 <\/p>
