Eutectic high entropy alloys (EHEA) with alternating FCC and BCC (B2) phases offer an excellent combination of strength and ductility. Additive manufacturing allows for the fabrication of ultrafine nanolamellar EHEA with directional growth. In this presentation, we show the effect of orientation on the deformation, strengthening, and fracture mechanisms of directional EHEA manufactured by additive manufacturing using in situ high-energy synchrotron X-ray diffraction and in situ high-energy synchrotron X-ray tomography. Our research sheds light on a better understanding of the co-deformation behavior of dual-phase alloys with orientation dependency. Moreover, our study provides insights into how to tailor the microstructure of additively manufactured directional EHEAs based on different mechanical property requirements.
