摘要

摘要介绍了一种新颖的实验室技术，用于在不使用炸药的情况下进行铜的微型累积射流试验。为了进行微累积试验，使用了带有锥形凹坑的微型圆柱形试样。试样的动态加载是使用带有加速到 800 米/秒的冲击器的气枪进行的。然后确定了最佳的试样几何形状和测试方法，包括微累积测试时的焦距。初步分析了铜的纯度和加工方法对最终动态塑性特性的影响。

A Method of Studying the Flow of Miniature Cumulative Jet of Copper

Abstract

A novel experimental laboratory technique for the flow of miniature cumulative jet of copper and without using explosives, is described. To perform the microcumulative tests, miniature cylindrical specimens with conical pits were used. The dynamic loading of the specimens was performed using a gas gun with a striker accelerated up to speeds of 800 m/s. The optimal specimen geometry and testing regimes, including the focal distance during microcumulation testing, were then determined. The influence of the structural condition of the sample material on the parameters of the cumulative jet has been demonstrated A preliminary analysis of the effects of copper purity and processing regimes on the ultimate dynamic plasticity characteristics was performed.

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
