The article presents the results of an experimental investigation of the effect of the temperature, the sulfur content, and
the previous heat treatment on the strength and fracture of the alloy 36NKhTYu under loading by shock waves. The load levels
corresponding to different stages of spalling fracture of specimens were determined in the temperature range from −196 to
750‡C. It was established that heating, increase of sulfur content, and hardening of the specimens lead to an imperceptible
decrease of the dynamic strength of the alloy. The article presents the results of observations of the structure and nature
of spalling fracture of the alloy by optical and electron microscopy.

The results are presented of experimental examination of the effect of the grain size on the spoliation of copper. Levels of the loading pressure, corresponding to various stages of spollation, were determined for two initial states characterized by a mean grain size of 0.29 and 1.62 mm. The results show that for the material with the smaller grain these levels are approximately 0.2 GPa higher than for the material with the larger grain size.Translated from Problemy Prochnosti, No. 2, pp. 73–75, February, 1996. 相似文献

We presents the results of damage of a carbon steel plate30 mm thick upon its loading by the impact of a steel ball5.55 mm in diameter at a velocity of up to7.4 km/sec. The dimensions of the crater formed and the bending flexure of the spalling layer are in good agreement with the results
obtained upon a less intense loading of the target. One more feature of damage, namely, a crack passing through the target
at the level of the crater bottom, has been revealed for the first time.
