Abstract Scope In situ nano/micro-mechanical testing in SEM, especially combined with analytical techniques such as EDS and EBSD, offers a powerful method for understanding the response of material microstructure to load or stimulus. However, running in situ experiments isn't trivial, often involving manual coordination of hardware and software dispersed across numerous platforms and vendors (electron imaging, analytics acquisition, in situ stage control). Further complications arise in data interpretation, with the challenge of correlating results in space and time originating from multiple sources. This contribution will present a fully integrated solution to mitigate these problems, combining a tensile-compression stage, heating unit, dedicated high temperature detectors, and EDS/EBSD sub-units controlled from a unified software environment. The user can prescribe automated runs with multiple ROI’s, implement automated feature tracking and autofocus, and define different imaging conditions or EDS/EBSD acquisition per ROI and load. Examples will be presented including copper, steel, and nickel alloy systems.
