An improvement in the ductility plasicity and the cleavage strength of Fe_3Al may result from adding Cr, it is more obvious at over 400℃. The Fe_2Nb containing Al precipitates in the Fe_3Al+Nb alloy, the particles provide significant strengthening. Additions of Cr and Nb in Fe_3Al provid a significant improvement in the yield strength at 550℃.
