STUDYING OF INTERFACIAL CONTACT IN THE Fe–Al POWDER MIXTURE BY DIFFERENTIAL THERMAL ANALYSIS

Abstract

The interfacial contact in exothermically reacting mixture of Fe and Al (or Al-alloys) powders calculated for the formation of Fe₃Al intermetallide formation is studied by deferential thermal analysis (DTA). The effect of alloying elements such as Mg and Ti on this process is analyzed. The behavior of the Fe–Al-based powder produced by heating under DTA conditions is compared with that of the powder with the same composition produced by mechanochemical synthesis.
