Creep mechanisms in Ti–3Al–2.5V alloy tubing deformed under closed-end internal gas pressurization

Creep tests were carried out on Ti–3Al–2.5V alloy tubing in the temperature range of 723–873 K under closed-end internal pressurization. The data thus obtained were analyzed to obtain the mechanistic creep parameters (stress exponent and activation energy). Transitions in creep mechanisms were noted...
