Abstract
Al3Ni20Bx alloys (0.06= x =0.12) nanocrystalline, AlNiB-NCys were synthesized by rapid solidification method in an arc-melt furnace or in an induction furnace. The effect of changing the addition ratio of boron on the crystallography, microstrural, crystal impurifications has been investigated for the Al3Ni20Bx ternary. The crystal structure of samples obtained using X-ray diffraction was examined. XRD analysis revealed that prepared samples have the polycrystalline nanometric face centered cubic structure. XRD-Line profile analysis by Lorentzian and Gaussian distributions were used to study the microstructure and crystal imperfections of Al3Ni20Bx. Crystallite size and microstrain were estimated using Williamson-Hall plots for the major eight XRD peaks. The data obtained shows that when the metal content is increased, the lattice parameters and volume of unit cell are increased linearly with boron concentration increase. This behavior is believed to be associated with an increase in content B by up to 11% that is entered into the unit cell of the Al3Ni20Bx system.
