Identifying the peculiarities of the transformation of the structure and properties of bulk metallic glass (BMG) under high-pressure torsion (HPT) is of great interest. It is known that under HPT, the degree of deformation differs from the center to the edge of a disk which leads to the non-uniformity of the structure of obtained specimens. The change in microhardness value indicates the direction of change in BMG structure under the HPT, and the microhardness distribution indicates the HPT-specimen non-uniformity. The aim of the study is to identify the HPT influence on the microhardness value and microhardness distribution over the surface of specimens of amorphous alloys using an example of Vit105Zr-based BMG (Zr52.5Cu17.9Ni14.6Al10Ti5). The authors studied the distribution of microhardness over the surface of Vit105 Zr-based bulk metallic glass (BMG) in the initial state, in the state after HPT at n=1 and n=5 rotations, and after relaxing annealing. The study shows that the initial Vit105 BMG is characterized by a small spread in microhardness values, which indicates the material's high homogeneity. By reducing the excessive free volume, relaxing annealing increases microhardness without a significant increase in the spread of its values. HPT leads to a decrease in the zirconium BMG microhardness, which indicates an increase in the excessive free volume, but, at the same time, increases the uneven microhardness distribution over the specimen, while the microhardness values in one half of the HPT sample (n=1) are higher than in the other one. It demonstrates that BMG specimen deformation during HPT is related to the specific loading mechanisms.

Большой интерес представляет установление особенности трансформации структуры и свойств объемных металлических стекол (ОМС) при воздействии интенсивной пластической деформации кручением (ИПДК). Известно, что при ИПДК степень деформации разнится от центра к краю диска, что приводит к неоднородности структуры получаемых образцов. Изменение величины микротвердости отражает направление изменения структуры ОМС при ИПДК, а распределение микротвердости – неоднородность ИПДК-образцов. Целью работы является установление влияния ИПДК на величину микротвердости и распределение микротвердости по поверхности образцов аморфных сплавов на примере ОМС Vit105 на основе циркония (Zr52,5Cu17,9Ni14,6Al10Ti5). Исследовано распределение микротвердости по поверхности ОМС Vit105 на основе циркония в исходном состоянии, в состоянии после ИПДК на n=1 и n=5 оборотов и после релаксирующего отжига. Показано, что исходные ОМС Vit105 характеризуются небольшим разбросом значений микротвердости, что свидетельствует о высокой однородности материала. Релаксирующий отжиг, снижая избыточный свободный объем, приводит к повышению микротвердости без значительного увеличения разброса ее значений. ИПДК приводит к снижению микротвердости циркониевого ОМС, что свидетельствует о росте избыточного свободного объема в результате деформации, но в то же время повышает неравномерность распределения микротвердости по образцу, при этом значения микротвердости в одной половине образца ИПДК (n=1) выше, чем в другой. Это показывает, что деформирование образца ОМС в процессе ИПДК обусловлено специфическими механизмами нагружения.
