Laves and B2 phases were engineered in serials of advanced ferritic alloys with the aid of computational alloy thermodynamics. The new materials were screened using tensile and creep tests and ion irradiations. Microstructure characterization was conducted for both the as-received and post-test conditions. It was illustrated that alloy elements such as Zr and Nb have a strong influence on the morphology and coherency of the Laves-phase precipitates likely through the interface configuration. The strengthening mechanisms of B2 and Laves phases were determined to be Orowan bypassing and dislocation/boundary pinning, respectively. It was found that B2 strengthening expires with a high level of material deformation. Irradiation-induced partial amorphization of Laves phase was observed, possibly leading to changes in mechanical property and radiation response of the material.
