Damage mechanisms at a microscopic scale of PM Ti-6Al-4V at 20 K
The microscopic damage mechanisms at cryogenic temperature of an extra low interstitial Ti-6Al-4V obtained by powder metallurgy (PM) are investigated. Through SEM observations and EBSD mapping, it is attempted to identify the microstructural features that control the damage. Damage nucleation as well as texture evolution with strain are particularly analyzed. It is shown that both features are closely related to twinning.
