The Kammrath & Weiss in situ mechanical testing platform (tensile-compression module) enables testing of macroscopic specimens within the ThermoFisher SEM Apreo 2S scanning electron microscope, while simultaneously observing the surface using secondary electron, backscattered electron, EDS, and EBSD detectors.
The equipment is designed for sub-standard specimens 30–60 mm in length, up to 10 mm in width, and 4 mm in thickness. It enables tensile, compression, and 3- and 4-point bending tests, with travel ranges of up to 45 mm, 0.1 µm resolution, force or displacement control, speeds between 0.1 and 20 µm/s, cyclic tensile/compression testing, and loads of up to 10 kN.
It includes load cells with different ranges to ensure adequate resolution, EBSD analysis capability to study deformation mechanisms in polycrystalline materials, video extensometry, and digital image correlation based on SEM images to analyze local deformation and damage evolution at high resolution.
