Crystal Structure of Al₂Cu₃Nd Ternary Compound

Abstract:

A new Al-Cu-Nd system alloy, the high-purity Al₂Cu₃Nd ternary compound, was developed and prepared with the stoichiometric amounts of elemental constituents by arc melting under argon atmosphere. The X-ray diffraction (XRD) data of Al₂Cu₃Nd was collected by using the Rigaku Smart Lab X-ray powder diffractometer, and all X-ray diffraction peaks of Al₂Cu₃Nd compound were indexed successfully with the hexagonal structure. The Rietveld refinement results of the XRD pattern for the Al₂Cu₃Nd compound showed that the Al₂Cu₃Nd compound is the hexagonal structure, space group P6/mmm (No.191) with a = 5.2397(1) Å, c = 4.1783(1) Å, V = 99.34 ų, Z = 1. The density of the compound was 6.501 g/cm³, and its reference intensity ratio (RIR) w 1.26.
