摘要：

The structural properties of a Zr62Cu22Al10Fe5Dy1 bulk metallic glasses were investigated. Cylindrical rods of the Zr62Cu22Al10Fe5Dy1 BMG were subjected to high pressure torsion at temperatures of 20 degrees C and 150 degrees C. X-ray diffraction, transmission electron microscopy were used to determine peculiarities of the modified structure. Analysis of fracture surfaces, nanohardness measurements were conducted to investigate the influence of structural changes on mechanical behavior of processed samples.
