| Abstract Scope |
The high flux and high energies at synchrotron sources make them ideal for non-destructive, grain-scale characterization of polycrystalline metals as they evolve over time. Advances in detector technology—such as the Dectris Eiger16M at the Structural Materials Beamline at CHESS—enable unprecedented sensitivity to signals of interest and acquisition rates relevant to real-world deformation processes. To match this capability, we present the Rotational and Axial Motion System IV (RAMSIV): a specialized load frame for in-situ synchrotron experiments. RAMSIV supports uniaxial, torsion, and combined loading, and uniquely allows the sample to rotate under load at speeds up to 400 deg/s while collecting data. This enables studies of complex thermo-mechanical response previously inaccessible in real time. This talk will highlight applications of RAMSIV in continuous loading and high-cycle fatigue, with rapid strain control using high-rate digital image correlation (DIC), demonstrating how these advances enable new insights into the dynamic behavior of structural materials. |
