Abstract

The microstructure of a polycrystalline Co annealed at 873. K, followed by furnace cooling to room temperature, was studied in this paper. It was found that a small amount of high temperature (above 690. K) face centered cubic (FCC) phase is retained after the slow cooling, and there is a Shoji-Nishiyama orientation relationship between the low temperature hexagonal close packed (HCP) and the retained FCC phases. Annealing twins were observed not only in FCC phase but also in HCP phase. A high fraction of special misorientation, 71.4°/(12̄10), was identified in the HCP phase, which was correlated to the phase transformation twins. © 2011 Elsevier B.V.
