Experimentation in a microgravity environment is a unique way to suppress these effects and to provide benchmark data for testing current theories of grain and microstructure formation. This contribution presents a summary of results obtained for directional solidification of Al-Cu alloys within the framework of the XRMON project. It is focussing on (i) the first ever microgravity experiment on solidification with in situ monitoring of metal alloys performed on board a sounding rocket and (ii) solidification experiments performed on board parabolic flights, where the effects of varying gravity level have been studied.enX-ray monitoringMicrogravity conditionsAluminium-copper alloysMASER 13 sounding rocketsConference Publication2020-05-19AO-2004-046 - CCN No.34200020288/06/NL/VJhttps://creativecommons.org/licenses/by-nc-nd/3.0/ie/
