摘要

本文给出了室温(18℃)下液态铋、锡、铅与水相互作用产生压力脉冲的实验数据。将所得的压力关系与视频记录的结果以及破碎产物的结晶形态进行了比较,从而为爆炸破碎过程的发展提出了合适的方案。实验在初始温度范围内进行,所研究的熔体质量分别为400 ~ 900℃和3 ~ 15 g。结果表明,高温液态金属液滴落入室温水中发生爆炸破碎,产生具有非晶结构的材料。以液态铋为例表明,随着体积的增大,材料的非晶性会增大。

Specific Features of the Breakup of Hot Liquid Metal Droplets Falling into Cold Water

Specific Features of the Breakup of Hot Liquid Metal Droplets Falling into Cold Water

The paper presents experimental data of pressure pulses generated by the interaction of liquid Bi, Sn, and Pb with water at room temperature (18°C). The resultant pressure relationships are compared with findings of video recording and with the morphology of crystallized fragmentation products, which allowed to propose an appropriate scenario for the explosive fragmentation process development. Experiments were performed in the ranges of initial temperature and investigated melt mass of 400 to 900°C and 3 to 15 g, respectively. It was confirmed that the explosive fragmentation of hot liquid metal droplets falling into room temperature water produce materials with amorphous structure. It is shown using liquid bismuth as an example that the amorphousness of a material can increase as its volume grows.

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.
