A time-resolved X-ray diffraction (XRD) experiment at 250 Hz using a synchrotron radiation source was carried out during the containerless solidification of ReFeO$$_{3}$$ (Re=Y and Lu) in order to identify the metastable phase ${it in situ}$. The metastable phase solidified primarily from the undercooled YFeO$$_{3}$$ melt finally transformed to the stable orthorhombic YFeO$$_{3}$$ phase during the short period of recalescence ($$sim$$0.035 s). Although the metastable phase could not be detected in the as-solidified sample by the powder XRD, the successfully obtained diffraction pattern of the metastable phase in the YFeO$$_{3}$$ system was consistent with that of the metastable hexagonal LuFeO$$_{3}$$ phase.
