The structure of Ni–enriched Al–Ni molten alloy before solidification
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 2
Abstract
The structure of Ni–based molten alloy, containing 88,02w.%Ni and dopped both with Zr (0,46w.%) and B (0,02w.%) has been studied by means of X–ray diffraction method at temperature 1500 K. Structure factor and pair correlation function were obtained from diffraction data and analyzed. Principal peak position in structure factor for doped molten alloy is compared with one for liquid Ni3Al intermetallics. Another structural parameters–most probable interatomic distance and number of neighbours have been also determined from pair correlation function and compared with parameters of crystalline structure for Ni3Al chemical compound. The structure data are interpreted with using of cluster models of metallic melts.
