Аннотация

A comparative study of the elastic properties of different types of metallic glasses (Ni78Si8B14 and Fe5Ni10Co60Si10B15) is made. A time relaxation of the density of states of two-level systems is observed and the physical nature of various contributions to the velocity of sound in the low-temperature region is discussed. By considering the example of the beryllium bronze BRB-2, it is shown that the disordering of alloys affects the behavior of the velocity of sound in them.
