The Ti-7 alloy was continuously deformed in uniaxial tension while FF-HEDM patterns were acquired. REI shows significant changes in three different ways. It increases significantly when the material undergoes elastic–plastic transition. It also changes when the incident flux changes significantly; an example of such an instance is highlighted by the purple ellipses. Furthermore, REI is sensitive to a gradual decay in the incident X-ray flux; an example of such an instance is highlighted by the dotted green (incident flux) and blue lines (REI). |
