brief introduction

The FT-NMT04 nanomechanical testing system is a multifunctional in-situ scanning electron microscope/fiber optic nanoindenter that can accurately quantify the mechanical behavior of materials at the micro and nano scales.

As the world's first based onThe nano indenter of MEMS, FT-NMT04, is based on specialized Femtotools microelectromechanical systems (MEMS) technology. With over 20 years of technological innovation, this in-situ nanoindenter has unparalleled resolution, repeatability, and dynamic response. FT-NMT04 in-situ nanoindenter is used for mechanical testing of microstructures such as metals, ceramics, thin films, metamaterials, and MEMS. In addition, by using various accessories, the performance of FT-NMT04 can be extended to meet the general requirements of various research fields. Typical applications include quantifying plastic deformation mechanisms through compression tests on micropores or tensile tests on bone specimens, films, or nanowires. In addition, continuous stiffness measurement during compression testing can quantify crack propagation and fracture toughness during micro beam fracture testing. Due to the unparalleled low noise flooring of 500 pn and 50 pm, FT-NMT04 shallow nanoindentation has unparalleled repeatability and unprecedented correlation between nanoindentation and EBSD mapping.
