Description
This book provides an in-depth exploration of the high-temperature thermophysical properties of the liquid state of metals essential for aerospace and nuclear applications. It begins by tracing the development of rapid electrical pulse heating, offering insights into its historical context and methodological nuances. Subsequent chapters delve into experimental investigations on key metals, including zirconium (Zr), hafnium (Hf), iron (Fe), gadolinium (Gd), tantalum (Ta), and tungsten (W), across the solid-to-liquid phase transition. Topics covered include thermal expansion, density, resistivity measurements, and phenomena such as explosive electron emission under nanosecond heating. In addition, it presents extensive and detailed tabular data on liquid-state metal thermophysical properties from original research previously unavailable in English. In sum, this book offers a rigorous examination of high-temperature metal properties, making it an indispensable resource for researchers, engineers, and students engaged in aerospace and nuclear disciplines.
