摘要	Two new ternary aluminum carbides, Hf(3)Al(4)C(6) and Hf(2)AW(5), were identified and their crystal structure was determined by a combination of X-ray diffraction, Z-contrast scanning transmission electron microscopy and density-function calculations. Theoretical second-order elastic constants, bulk modulus, shear modulus and Young's modulus of Hf(3)A(14)C(6) and Hf(2)Al(4)C(5), as well as Hf(3)Al(3)C(5), Hf(2)Al(3)C(4), HfC and Al(4)C(3), were calculated and compared. These new carbides show promisingly high elastic stiffness. (C) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
