Abstract

The microstructural characteristics of the Fe-9Al-30Mn-1C-5Ti (wt.%) alloy were determined by scanning electron microscopy, transmission electron microscopy, and energy-dispersive X-ray spectrometry. The microstructure of the alloy was essentially a mixture of (γ + TiC_x + (α + B2 + DO₃)) phases during solution treatment between 950 °C and 1150 °C. The TiC_x carbide had a face-center-cubic structure with a lattice parameter a of 0.432 nm. When the as-quenched alloy was subjected to aging treatment at temperatures of 450-850 °C, the following microstructural transformation occurred: (γ + TiC_x + κ + (α + DO₃)) → (γ + TiC_x + κ + (α + B2 + DO₃ + TiC_x)) → (γ + TiC_x + κ + κ′ + (α + B2 + DO₃)) → (γ + TiC _x + (α + B2 + DO₃)). Addition of Ti promotes the formation of the α phase at high temperatures.
