By replacing the high irradiation active alloying elements with the low ones,reduced activation ferritic/martensitic(RAFM)steels were developed from the conventional ferritic/martensitic steels.RAFM steels and their oxide dispersion-strengthened variants have been investigated as the primary ITER and future DEMO blankets up to now.Nonetheless,there has been no detailed study of the effects of the substitutional solutes with dilute concentrations on the mechanical properties of α-Fe.In this paper,elastic moduli of bcc Fe1-xMx(M=Al,Si,Ti,V,Nb,Cr,Mo,W,Mn,Co,Ni and Cu; 0.4≤x≤6.25 at%)solid solutions are arithmetically extracted from first-principles calculations of stress,and solid-solution strengthening effects of these solutes are evaluated based on Labusch-Nabarro model.Effects of vacancy and substitutional helium on the mechanical properties of α-Fe are also investigated in this paper.
