Description
Summary:•The interactive interface between face-centered cubic (FCC) phase and {101¯1}twin is finely characterized by HRTEM.•The FCC-Zr phase and the matrix follow B-type orientation relationship, but the interface deviates from (0001) habit plane.•A new orientation relationship is formed between the FCC-Zr phase and {101¯1} twin: HCP// FCC and {101¯1}HCP//{11¯1}FCC. The thermally induced face-centered cubic (FCC) phase and its interactive interface with {101¯1} twin in Zr–1.0Sn–1.0Nb–0.3Fe alloy were characterized via transmission electron microscopy. The FCC-Zr phase and the matrix have a B-type orientation relationship, however, the interface deviates from the (0001)HCP habit plane. Moreover, the FCC-Zr phase and the twin follow Py-type orientation relationship, namely HCP//FCC and {101¯1}HCP//{111}FCC, which may be attributed to expansion and shuffling adjustment. Although the Py-type orientation relationship between the hexagonal close-packed and the FCC phases in Zr is rarely observed, due to the large crystal plane mismatch, this study provides intuitive evidence of this relationship.
