Abstract

A series of ternary alloys has been prepared by adding either Cr or Ti to replace the Fe in binary Fe₃Al. The effect of these additions on the phase structure has been determined using microscopic, magnetic, and electrical techniques. For small substitutions of Ti for Fe, there is an increase in the DO₃qqB2 transition temperature. Substitution of Cr for Fe does not change the DO₃qqB2 transition temperature. When either Ti or Cr is substituted for Fe at concentrations up to 7 at.% no new phases result, however, electrical resistance measurements indicate that the ordering process is modified, so that with increased solute disordering begins at a lower temperature as the DO₃qqB2 critical temperature is approached upon heating.
