摘要：

Microstructure and mechanical properties of V-4Ti-4Cr alloys subject to their thermo-mechanical processing (TMP) regimes were investigated. As a plastic deformation technique was used multiple multidirectional forge molding (MDFM) that removes restrictions on the plastic deformation value and the number of TMP cycles while the specimen shape is maintained. The use of MDFM results in finer grain size and more uniform spatial distribution of the secondary phase particles. Also it allows to form fine-crystal structural states in the final TMP stage and brings significant increase in high-temperature short-time strength of the alloy. (C) 2011 Elsevier B.V.
