eng	Microstructure Development of Fe2Si5 Thermoelectric Alloys During Rapid Solidification, Hot Pressing and Annealing	Fine crystallinity may improve the figure of merit of iron disilicide-based thermoelectric materials. Manganese doped iron disilicide based alloys with the chemical composition of Fe1.92Mn0.08Si5 have been prepared by rapid solidification and hot uniaxial pressing (HUP), and the microstructure development during the preparation has been studied. Textures have been found in the annealed samples hot-pressed from the melt spun ribbon powders. Large polyhedral silicon grains with a size of about 2 m and small silicon rods about 200 nm in diameter have been observed in the annealed samples, which are considered to be formed during HUP at about 900 °C and annealing at 800 °C, respectively	iron disilicide;transition metal compounds;rapid solidification;thermoelectric;microstructures
