Abstract
This paper looks at ways to improve the characteristics of rapid steels. The authors try to understand how the microstructure changes during aerothermoacoustic treatment in comparison with conventional heat treatment techniques and what changes are typical of rapid steels under the aforementioned treatment. The main result of this work is an understanding of how different aerothermoacoustic treatment regimes influence the behavior of rapid steels. It was established that aerothermoacoustic treatment can be used to enhance the strength characteristics of rapid steels. A qualimetric analysis was carried out to estimate the effect of aerothermoacoustic processing on the characteristics of tool steels.
