Purpose: This paper presents the results of the research focused on the influence of both the starting FeAl alloy powder particle characteristics and the thermomechanical processing parameters on the microstructural evolution of these materials. Design/methodology/approach: Fully-dense FeAl alloy powder compacts were tested in compression on servohydraulic Gleeble testing machine, at the temperature range of 700*C to 1100*C, and at strain rates of 0.1 s ^-1 and 10 s ^-1. After processing, the microstructure of each deformed specimen was examined using optical microscopy. Findings: Considerable strain rate sensitivity of the investigated alloy was observed, especially with reference to microstructural development. The use of alloy powders in thermomechanical processing of FeAl alloys can substantially enhance the possibility to control both the microstructure and mechanical behavior of these alloys. Research limitations/implications: The influence of starting FeAl alloy powder particle morphology and processing strain rate on the microstructural evolution of investigated alloy was discussed. Practical implications: The results of this research could be directly employed in the design of deformation schedules for the industrial processing of FeAl alloys. Originality/value: FeAl alloy powder morphology influences the thermomechanical processing of P/M FeAl alloys, what was proved in this paper.
