X-RAY DIFFRACTION STUDY OF ICOSAHEDRAL PHASE IN RAPIDLY QUENCHED A1-Mn

Variation of the correlation length of icosahedral phase with the annealing temperature is got according to the broadening of the X-ray diffraction peak. The fact that the correlation length does not change during the crystallization process means that the grains of icosahedral phase are transformed wholly and perfectly to crystalline Al₆Mn.
