Annealing behavior of severely-deformed titanium Grade 4
The annealing behavior of severely-deformed commercial-purity titanium Grade 4 was determined. To this end, the material was subjected to 12 successive ECAP-C passes at 200 °C (0.24 T m) and then isochronally annealed between 50 °C (0.16 T m) and 850 °C (0.57 T m) for 1 h. To preserve the microstructure, each annealed sample was …
