摘要	Crystallographic texture control is the critical challenge for directionally solidified eutectic (DSE) ceramics. We herein report a high-entropy (Y0.2Gd0.2Ho0.2Er0.2Yb0.2)3Al5O12/Al2O3 DSE ceramic that shows outstanding crystallographic texture formation capability. Based on comprehensive observations of phase composition and eutectic microstructure characteristics, the single crystal phases of high-entropy (5RE0.2)3Al5O12 (RE = rare earth) and Al2O3 are obtained within a much-shortened growth distance (within 15 mm) than those of the single rare earth containing RE3Al5O12/Al2O3 counterparts (typically >= 80 mm). The rapid formation of stable crys-tallographic texture is significant for microstructure control in DSE processing and uniformity of mechanical property along the whole material.
