Abstract
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.
