Abstract

Microstructures of La-Cu-Ni-Al alloys of rod samples with 12 mm diameter prepared by copper mould casting along La_86-x [Cu_0.5Ni_0.5]_xAl₁₄ compositional line were studied by scanning electronic microscope (SEM) observation, and X-ray diffraction (XRD). Glassy rod with diameter of 12 mm can be formed by copper mould casting. The alloy has a composition near to La₆₂[Cu_0.5Ni_0.5 ]₂₄Al₁₄, and has a very narrow supercooled liquid region, ΔT_x=29 K, (ΔT_x=T_x -T_g, where T_x is the onset crystallisation temperature and T_g is glass transition temperature).
