High-energy proton and neutron radiation change the microstructure and composition of structural materials during operation. These changes typically cause an increase in the strength and decrease in the ductility of the material with increasing dose. Administrative lifetime limits are applied to components in high-radiation environments at the Spallation Neutron Source (SNS) to limit the risk...
In this presentation, we showcase the latest capabilities and breakthroughs achieved in our laboratory using state-of-the-art instruments, namely the dilatometer, differential scanning calorimeter (DSC), and nano-indenter. Through rigorous experimentation, we have examined the thermal and mechanical properties of various materials, including conventional materials such as graphite and titanium...
Tungsten is chosen as the target material of European Spallation Source (ESS) where it will be irradiated by a high energy (2 GeV) and high power (5 MW) pulsed proton beam to produce neutrons to be used by neutron scattering intruments. For designing a target with a high availability, it is important to determine the development of the temperature and secondary thermal stresses in tungsten...
Austenitic stainless steel is used as a container material for spallation neutron source targets such as the American spallation neutron source (SNS), the Japanese spallation neutron source (J-PARC), and the Chinese spallation neutron source (CSNS), due to its excellent high-temperature performance, welding performance and corrosion resistance. There are some researches on the performance of...
Because of outstanding thermal conductivity of 160-230 W m-1 K-1, high water corrosion resistance and good radiation tolerance, as well as comparably low-radioactivity elements, Al alloys have been used as components in fission reactors [1]. To be noted, the Al–2.7wt%Mg (AlMg3) alloy has been used until now as the beam window material for the safety-hulls of the targets of the Swiss Spallation...
