Abstract
Experimental investigations of the properties of nanostructured materials are of large practical significance. Physical and chemical properties of nanocrystalline and amorphous-nanocrystalline alloys are currently being actively researched. Yet, the practical use of such materials is complicated by the lack of an optimal set of physical and mechanical properties. Classical processing methods are not effective enough. Laser processing is a promising method for forming specified mechanical properties. Amorphous-nanostructured materials, as a result of local and ultrafast exposure to high temperatures and pressure, retain their structure almost unchanged. At the same time, plasticity and microhardness can remain at a high level, and in some cases even increase during processing. The relevance of the presented work lies in the study of the regularities of the simultaneous increase in plasticity and microhardness of an amorphous Co-based nanocrystalline metal alloy, due to its processing with nanosecond laser pulses. The relevance of the presented work lies in the study of the patterns of the simultaneous increase in plasticity and microhardness of an amorphous Co-based nanocrystalline metal alloy due to its processing with nanosecond laser pulses.
