Abstract

Crystal structure, phase fraction and texture of long period stacking ordered structure (LPSO) phase in ternary Mg–Zn–Y alloys have been investigated by analysis on time-of-flight (TOF) neutron diffraction profiles using the Rietveld method. It has been shown that the LPSO phase in the alloys is 18R-type structure of space group <i>P</i>3<sub>2</sub>12 with <i>a</i> = 1.1182(0) nm and <i>c</i> = 4.7032(5) nm. The LPSO phase shows very strong [10\bar{1}0] texture parallel to the growth direction in a directionally-solidified crystal alloy.
