A reassessment of the Al-Fe system using a four sublattice model for the DO 3 ordering

April 9, 2009
Author(s)
Ursula R. Kattner, Bo Sundman, Ikuo Ohnuma, Nathalie Dupin, S Fries
The Al-Fe system is important in many alloys and the new interest in iron aluminides makes it necessary to improve the modelling of the different ordered forms of the A2 lattice in this system. This has now been done using a 4 sublattice model based o the
