Abstract

Highlights: Intermediate state of B-type FCC zirconium phase was firstly reported. B-type FCC phase obey the path of HCP→Intermediate state→FCC. Intermediate state is direct evidence of FCC phase via partial dislocation. Abstract: An intermediate state of basal-type (B-type) face-centered cubic (FCC) zirconium phase is firstly reported in as-solidified pure zirconium by means of transmission electron microscopy (TEM) technique. The B-type hexagonal close-packed (HCP) to FCC phase transformation can be realized by following path: HCP→Intermediate state→FCC and each stage contained Shockley partial dislocations with Burgers vector of 1 / 6 [ 0 1 ¯ 10 ] . The observed intermediate state is direct evidence of the B-type FCC zirconium phase via partial dislocation.
