Multi-phase High Entropy Alloys (HEAs) are a new class of materials with excellent combination of properties. In the present work, a TWIP/TRIP assisted dual phase interstitial Fe49.5Mn30Co10Cr10C0.5 HEA is subjected to single-pass and multi-pass friction stir processing. A fine grain microstructure is obtained due to the severe plastic deformation produced as a result of friction stir processing. Nanoindentation is performed to characterize the microstructural dependent mechanical properties of different processing zones, viz., the stir zone, the heat affected zone and the thermo mechanical heat affected zones on the advancing and retreating sides in samples subjected to both single pass and multi pass friction stir processing. Hardness and elastic modulus of multi pass friction stir processed sample is found to be better than that of single pass.
