Abstract
The DO3-type ordering in Fe-28Al and Fe-28Al-1.5Mn alloys are investigated by TEM and XRD. The results show that Mn addition into DO3-ordered Fe3Al al loy could decrease degree of ordering. Two major factors are considered to have effect of Mn on ordering behaviour of the alloy: reducing grain size a nd reducing antiphase domain size. The further investigation of deformed an tiphase boundaries and slip lines in the alloy with Mn addition suggests th at Mn could promote slip and cross slip in DO3 Fe3Al alloy during deformati on.
