摘要

摘要提出了一个简单的原子等离子体物理模型，通过该模型可以计算难熔金属在近临界区的状态方程，并获得汽液相变临界点的参数，包括二极值。该模型的一个特点是利用内聚力（金属中原子内聚力的集体能量）考虑了原子间的相互作用。对许多难熔金属的临界点参数进行了估算，包括临界点的电导率。

The Problem of the Equation of State of Refractory Metals in the Near-Critical Region

Abstract

A simple physical model of atomic plasma is proposed, which makes it possible to calculate the equation of state of refractory metals in the near-critical region and obtain the parameters of the critical point of the vapor–liquid phase transition, including the binodal. A special feature of the model is that it takes into account interatomic interaction using cohesion—the collective energy of the cohesion of atoms in a metal. Estimates of the critical point parameters for many refractory metals, including the conductivity at the critical point, are obtained.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
