Method of quantitative estimates of the parameters of the icosahedral quasicrystals substructure, including specific phason defects, developed and successfully worked out using the experimental models of quasicrystalline Al₇₀Pd₂₁Re₉, Ti₄₁.₅Zr₄₁.₅Ni₁₇ and Al₆₄.₅Pd₂₁Mn₁₄.₅ with different preparation technology. The method is based on the analysis of the diffraction lines' width of complete X-ray diffraction pattern. The results are in a good agreement with the prehistory of the samples.
