Figure 8
The in situ stress–strain curve of the CP-Ti alloy sample (yellow dots) and associated REI results (blue dots) in the elastic and elastic–plastic transition regimes. REI remains roughly constant in the elastic regime. As the material approaches its macroscopic yield point, REI also starts to increase significantly, highlighted by the purple ellipse, and it continues to increase as the plastic regime sets in. The abrupt change in REI near 0.1 strain is due to a beam size change between two target load levels; this is discussed further in Section 3.4 ![]() |
