Application of resonant nuclear reactions for studying the diffusion of nitrogen and silicon in ti-modified stainless steel

Abstract

Resonant nuclear reaction analysis can be used for the study of diffusion behaviour of minor alloying elements in reactor structural materials. In the present paper, 15 N(p, ) 12 C and 30 Si(p, ) 31 P reactions have been used to profile the ion-implanted 15 N and 30 Si in D9 alloy (titanium-modified austenitic stainless steel). The diffusion coefficients at various temperatures have been estimated from the broadening of the implantation profiles during thermal annealing, and the activation energies are deduced.
