FeMnCoCrAl with 0.7at%C powders were gas atomized, consolidated by laser powder bed fusion and heat treated by hot isostatic pressing technique. Microstructures of different manufacturing steps were characterized (SEM-EDS-EBSD, TEM, XRD) and stress-strain behavior as well as deformation mechanisms (TWIP and TRIP) of consolidated specimens were studied with in-situ-SEM tensile tests. Engineering and true stress-strain curves as well as EBSD phase maps showing the deformation induced martensitic transformation as a function of strain are presented.
