The Zr inclusions in this study were found to be FCC, rather than HCP α-Zr. The first observation of an HCP to FCC transformation in Zr was made in 2002 during ball-mill mechanical attrition of pure Zr and again in 2017 during the cold-rolling of pure Zr . Therefore, additional research is needed to determine whether the FCC structure was ...
