%X The effects of Cr and Nb on tensile properties at room and elevated temperatures and also onthe microstructure have been investigated.An improvement in ductiliy plasicity and thecleavage strength of Fe_3AI may result from adding Cr;the improvement is more pronouncedat over 400℃.The formation of Fe_2Nb containing A1 precipitates in the Fe_3AI+Nb alloyprovide significant strengthening effect.Additions of Cr and Nb in Fe_3AI can cause a signifi-cant improvement in the yield strength at 550℃.
