Deuterium and helium trapping at TiC particles in ferritic steel

摘要: Abstract First wall and blanket materials in Tokamak machines must accommodate increasing concentrations of helium hydrogen isotopes. Alloy design principles point to the efficacy trapping He at finely dispersed precipitates minimize their impact on mechanical properties. Titanium carbide particles are known trap effectively austenitic stainless steel. Less is about TiC as a for isotopes ferritic steels. This paper demonstrates feasibility directly measuring deuterium TiC-ferrite interfaces using atom probe field ion microscopy.
