Abstract

A alloy Al_1.5Cu_3.5Nd was synthesized by experimental methods. The phase composition of the alloy after high temperature annealing was observed and analyzed by scanning electron microscopy. It indicates that the alloy is a single-phase alloy with uniform chemical composition. Then, the powder x-ray diffraction patterns of the compound were collected for Rietveld refinement. The results of Rietveld refinement show that Al_1.5Cu_3.5Nd is isostructural with AlCu₄Nd, crystallizes in hexagonal CaCu₅-type structure, the space group is P6/mmm (No.191), its lattice constants a, c, unit-cell volume V, formula units per unit cell z, and calculated density ρ_x are 5.1707(3) Å, 4.2011(2) Å, 97.27 Å³, 1, and 6.95 g/cm³, respectively. The residual factors are R_p = 3.31%, R_wp = 4.35% and R_exp = 2.87%.
