Abstract To measure the temperature of shaped-charge jets, we fabricated three-layer copper–copper–Constantan liners consisting of a solid copper conical shell with a cone angle of 45° and a wall 1.5 mm thick and a shell pressed into it and rolled from a 1.0 mm thick copper sheet clad on the inside with a Constantan layer 0.5 mm thick by explosive welding. Then, the Constantan layer was partially removed so that only the upper third of the inner surface of the shells remained lined with Constantan. The thickness of the Constantan layer was chosen such that the head of the shaped-charge jet consisted only of Constantan, and the tail of copper, as determined from a thin section of the recovered slug. As a result, a copper–Constantan thermocouple was formed. At the moment of impact of the bimetallic jet on a target, the thermo-EMF signal was measured with an oscilloscope. The obtained thermo-EMF value corresponds to a temperature of 800 ± 80.

锥形衬管成形电荷射流的温度测量

摘要 为了测量聚能射流的温度，我们制造了三层铜-铜-康铜衬里，由一个锥角为 45°、壁厚为 1.5 mm 的实心铜锥形壳和一个压入其中并轧制的壳组成。由 1.0 毫米厚的铜板通过爆炸焊接在内部包覆 0.5 毫米厚的康铜层。然后，部分去除康铜层，使得仅壳内表面的上三分之一保留有康铜内衬。选择康铜层的厚度，使得聚能装药射流的头部仅由康铜组成，尾部由铜组成，这是从回收的段塞的薄部分确定的。结果，形成了铜-康铜热电偶。在双金属射流撞击目标的瞬间，热电动势信号是用示波器测量的。获得的热电动势值对应于 800 ± 80 的温度。
