## Abstract The mechanical behavior of the Ti‐6Al‐4V ELI alloy in both conventional grain size (CG) and ultrafine‐grained (UFG) conditions under tension and compression at elevated temperatures (500–800 °C) is considered. Grain refinement by equal‐channel angular pressing (ECAP) followed by multicy
## Abstract We have presented a formation of ultrafine‐grained microstructure (d~α~ ≈ 0.2 µm) of industrial Ti–6Al–4V alloy produced by the hot compression of a sample with the acicular α′ martensite starting microstructure. The hot‐deformation behavior was different from the case of the convention
