Abstrakt

Severe plastic deformation using high-pressure torsion leads to a partial destruction of the B2 long-range order in FeAl. Transmission electron microscopy methods reveal that chemically ordered nanodomains of medium-range size (about 2 nm) are formed. These nanodomains are separated by antiphase boundaries and homogeneously distributed within the grains. Upon heating, the order is restored by coarsening of the ordered nanodomains until the size of the ordered domains reaches the grain size.
