Development of Experimental Techniques Using LVP (Large Volume Press) at GSECARS Beamlines, Advanced Photon Source

Abstract

GSECARS (GeoSoilEnviroCARS, the University of Chicago) operates a bending magnet and an undulator beamlines at Sector 13, Advanced Photon Source. Experimental technique for High Pressure X-ray Tomographic Microscope (HPXTM) using monochromatized X-rays has been developed. The module for HPXTM also has shear deformation capability, which enables us to perform HPXTM experiments for microstructure developed by shear deformation under high pressure. A combination of Deformation DIA (D-DIA) and monochromatic X-rays has been developed for quantitative deformation experiments under pressure above 10 GPa. Deformation experiments of ε-iron was performed at pressures up to 19 GPa and temperatures up to 700 K.
