摘要：
The precipitation of vanadium carbides in idiomorphic ferrite, which was deliberately produced at a large prior austenite grain-sized condition, in a vanadium-containing medium-carbon steel has been investigated. Transmission electron microscopy reveals that in the idiomorphic ferrite matrix, the interphase-precipitated carbides can be intimately connected with the fibrous carbides. Through the analysis of orientation relationships, the correlation between these two precipitation modes has been proposed. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd.
