摘要：
We report on single-crystal growth of the equiatomic FeCoCrMnAl high-entropy alloy by means of the Bridgman technique. Our crystals are about 1 cm in diameter and 6.6 cm in length. X-ray Laue images taken at various positions on their surface are sharp and mutually consistent. The material has a microstructure consisting of B2 inclusions in a body-centred cubic matrix. The inclusions are {0 0 1} platelets of about 65nm thickness with varying lateral extensions of the order of 500 nm, predominantly containing Al and Co. The matrix is rich in Fe and Cr. [GRAPHICS] IMPACT STATEMENT We report the growth of a cubic-centimetre-sized single crystal of a high-entropy alloy. We characterize a Bridgman crystal of the equiatomic FeCoCrMnAl phase and analyse its two-phase structure.
