Abstract and subjects
In situ phase transformation experiments have been carried out using neutron diffraction to monitor the texture evolution during the alpha -> beta -> alpha phase transformation in a common zirconium alloy. In contrast to recently reported results by other authors, there is clear evidence of a strong variant selection occurring during the alpha -> beta transformation and a weaker variant selection during the beta -> alpha transformation. Modeling of the texture change associated with the phase transformation has been successful in describing the variant selection occurring during the alpha -> beta transformation, and gives insights into the selection occurring during the beta -> alpha transformation. The results are relevant to processing of both zirconium and titanium. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
