Microstructural evolutions during HDDR phenomena in Sm₂Fe₁₇ particles were observed by transmission electron microscopy. Sm₂Fe₁₇ compounds heat-treated over 510°C in a H₂ atmosphere disproportionate into SmH₂ and α-Fe phases with crystal relationship of α-Fe {110} // SmH₂ {111}. Recombination reactions were initiated by desorbing hydrogen from SmH₂ phases, and α-Fe phases diffuse into SmH₂ particles to form Sm_{2 + δ}Fe₁₇ phases by recombination. Prolonged aging in vacuum forms Sm₂Fe₁₇ fine grains of 100-300 nm in diameter.
