Samenvatting

A number of low temperature features are revealed: nonmonotonic temperature and anomalous strain-rate dependence of the strength, correlation between the concentration dependence of the strength with the atomic short-range order and some thermodynamic characteristics of the alloys, nonuniform microhardness from layer to layer in the bulk of the ribbon. Amorphous metal alloys (AMA’s) have some peculiar properties making them interesting in terms of both physics and application. This chapter is a brief review of the results of investigations of the mechanical properties of AMA’s (ribbons and bulk compacts) in relation to their structure at temperatures between 1. 5 and 300 K. The structure of alloys was varied in various ways: by changing the concentrations of the component elements; by preannealing at above room temperature; by using various deformation rates; by varying the stressed state of the material near a propagating crack in amorphous ribbons; by varying the state of the surface of the ribbons.
