Abstract
The grain growth of β region and the microstructural alteration of α phase depending on the various solution treatments have been studied in Ti-6Al-4V alloy. In specimens solutionized in β region, the grain size of β phase increase with increasing the temperature and the holding time. The hardness also increased with increasing temperature, but was nearly constant with increasing holding time, regardless of the grain size of β phase over 0.7㎜. In the specimens solutionzed in α+β region, as the solutionized temperature increased, the volume fraction of primary α phase and the vanadium content in α phase and α′+β phase decreased linearly. This seems to cause the decreasing hardness with increasing temperature. The Ms temperature of the specimen solutionized to vary matrix stucture has been shown to decrease about 25℃ than in the specimen of solution treated to vary volume fraction of β phase.
