中文摘要	Microstructure refinement of a dual phase titanium alloy, Ti-3Al-4.5V-5Mo, by severe room temperature compression was investigated. Nanocrystalline grains were observed in the sample with 75% reduction, in which the grain sizes of alpha phase and beta phase were approximately 50 and 100 nm. Conversely, the average thicknesses of alpha phase and beta phase in as-received microstructure were measured to be 0.7 and 0.5 mu m, respectively. TEM and XRD methods were used to analyze the microstructure and texture changes after severe deformation. Microstructure refinement was deduced to the complex interaction among slip dislocations in the alpha phase, the complex interaction among slip dislocations and martensites in the beta phases. In addition, the interaction between the alpha phase and the beta phase also contributed to the microstructure refinement.
