ABSTRACT=<p>FeCrAl alloy is a promising candidate material for the fourth-generation reactor core cladding material. Adjustment of the Cr content is one of the effective ways to obtain enhanced performance for the FeCrAl alloy. In this work, Fe–<italic>x</italic>Cr–6Al alloy (11 ≤ <italic>x</italic> ≤ 15) with different Cr content were successfully prepared by hot rolling. When Cr replacement of Fe atoms in Fe–<italic>x</italic>Cr–6Al alloy rises from 11 to 15wt%, the lattice distortion of Fe–<italic>x</italic>Cr–6Al alloy increases, and the mechanical properties and thermal conductivity of the Fe–<italic>x</italic>Cr–6Al alloy are raised. Compared with Al content, Cr content has less effect on Fe–<italic>x</italic>Cr–6Al oxidation resistance.</p>
