Materials Characterization

Materials characterization utilizes various optical and electron-optical microscopy techniques for atom and crystal scale structural analysis, and X-ray diffractometry for phase, structure and residual stress analysis. Thermal analysis equipment is used for thermal and dynamical material property determination. The mechanical test facilities include various electro-mechanical and servo-hydraulic materials testing machines for tensile, compression, and fatigue testing in a wide range of temperatures.

The High Strain Rate Research Laboratory has several Hopkinson Split Bar devices, allowing tensile and compression testing in the strain rate range of ca. 500…5000 1/s in a wide range of temperatures. The laboratory has also several high speed cameras combined with 3D digital image correlation (DIC) capabilities.
