The microstructure and precipitates’ evolution after hot deformation of Zr−Sn−Nb−Fe samples in the α and α + β phases are investigated using transmission electron microscopy (TEM), energy dispersive x-ray spectroscopy (EDS), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) accessories. The results show that the grain structure of the hot-deformed Zr−Sn−Nb−Fe-alloy samples is elongated along the thermal-deformation direction, forming a long, strip-like structure. Numerous recrystallized small grains and subgrain boundaries exist between these strips. The precipitated phases in the deformed samples with increasing temperature are primarily β-Zr, with minor amounts of β-Nb and Zr(Fe, Nb)2, exhibiting a relatively uniform dispersion.

Key words: Zr−Sn−Nb−Fe alloy, hot deformation, microstructure, precipitate phase.
