The Alemnis system has been used for thousands of studies in the materials science domain, covering all classes of materials (metals, polymers, ceramics, composites) and many different test methods (micropillar compression, tensile testing, indentation, beam bending, mapping, fracture toughness, fatigue and shock, impact, creep, stress relaxation, scratch testing, tribology, etc..). It can be operated in-situ in Scanning Electron Microscope (SEM) or other closed environment (vacuum chamber, nuclear hot chamber, etc.) or ex-situ on a laboratory bench or in a synchrotron beamline. In addition, the Alemnis technology can be combined with many other complimentary techniques, such as Electron Backscatter Diffraction (EBSD), X-ray, tomography, Raman spectroscopy, electrical, electro-chemical, Atomic Force Microscopy (AFM), optical microscopy, confocal microscopy, to name but a few…
