N2 - The surface morphology of B2-structured FeAl single crystals is modified on a nanoscale by the absorption process of supersaturated thermal vacancies. A high density of nano to mesoscale surface pores is successfully produced by the vacancy absorption process through water quenching, surface treatments, and aging heat treatment. Their shape, size, and density can be controlled by varying the surface orientation of single crystals, quenching temperature, aging temperature, and aging time. These results suggest that surface self-patterning by the vacancy absorption process is a useful bottom-up technique for obtaining nanoscale surface patterns in metallic materials.
