N2 - Five ferritic alloys and a ferritic-martensitic steel, designed by computational thermodynamics using recently developed database, were assessed in this work. A previous Fe-Cr-Zr ferritic alloy, named as Z6, was further investigated because of its amorphization behavior after a peak damage of 50 displacements per atom (dpa) at 400°C. Alloying elements of Zr, Nb, and Mo were varied to form four new ferritic alloys, named as Z1N33A, BL-Nb, BL-NbZr, and BL-Mo, which have reduced Zr-bearing Laves phase and complemented with B2-NiAl phase. The ferritic-martensitic steel, named as TTZ2M, favored MX-type (M=metal, X=C/N) precipitates with controlled M23C6 and Laves phases.
