Аннотация:A Zr-based bulk metallic glassy sample was subjected to the mechanical compression test at room temperature. The elastic modulus variation in the surface regions near and far from a shear band with a shear step of about 2 μm was measured using modulus ulus decreases the near atomic the gradually force shear microscope band's towards central the (AFM) shear region quantitative bands is about mid-plane 70% nanomechanical on onnanometer the micrometer mapping scale. scale. method. SuchMaximum a huge It was increase found decrease that in elasticity in Young's the Young's mod close to the central plane of the shear band is attributed to the generation and migration of the excess volume during the shear band operation and possible formation of nanovoids.
