Study of the Influence of the Shape of Internal Cavities on the Nature of Wave Strain Hardening

Abstract:

The results of a study of the influence of shapes of samples, as well as the presence of internal cavities and their shapes, on the nature of wave strain hardening (WSH) are presented. The peculiarity of the method lies in the impact of a stream of pulses on the processed material, while instant wave states, which affect the microhardness maps in the workpiece are formed in the material. These studies were carried out for the first time on a specially designed stand. The studied grades of materials were: steel 45 and bronze BRAZH 9-4. As a result of the studies performed, the geometric shape of the samples and cavities in them was revealed, which contribute to an increase in microhardness.
