Characterization of the Flow Behavior of a Ti6Al4V Alloy Considering the Temperature Change of the Specimen During Cylinder Compression

There are several methods of revealing temperature effect in hot cylinder compression test on actual flow curves. However, few methods were verified by the direct comparison between the experimental and predicted compression load-stroke curves. In this study, the systematic and scientific method of obtaining the flow curves formulated by the generalized C–m model considering the actual test environments is applied to the temperature-sensitive Ti6Al4V alloy in the temperature range of warm forming. Finite element analyses of the cylinder compression tests are conducted at various sample temperatures and strain rates using the fitted flow function, revealing that the predicted compression load-stroke curves are consistent with the experimental results.
