• [Display omitted] •Distribution of elastic properties (the Young’s modulus) in the deformed sample.•The scale of nonuniformity in the samples with numerous deformation bands.•The size of the regions with the low Young’s modulus around the shear bands. Distribution of mechanical properties around the shear bands inAl87Ni8La5 amorphous alloy was studied by atomic force microscopy (Peak Force QNM). The amorphous alloy was subjected to cold rolling. The deformation value was 50%. Numerous shear bands were observed in the alloy samples after the rolling. It is shown that inhomogeneity of the distribution of local properties (inhomogeneity of the distribution of the effective Young‘s modulus) arises in the deformed sample. The inhomogeneities form a system of bands. The thickness of the bands is 50–250 nm. Location of the regions of the low Young’s modulus correlates with location of the shear bands.
