Abstract

The paper discusses density and molar volume of liquid alloys of iron with C, B, Si, P, Cu, Al, Ni, Cr and Mn. Liquid alloys of iron with other metals are considered as substitutional solutions using the hard-sphere model. Deviations of molar volumes of Fe-Cu and Fe-Al alloys from the ideal solutions were analysed using relationship between excess volume and entropy. Alloys of iron with Ni, Cr and Mn are close to the ideal solutions. Calculated volumes are in agreement with experimental data. Alloys of Fe with C, B, Si and P are considered as interstitial solutions using P. Gaskell�s model developed for amorphous alloys of transition metals with metalloids. Calculated partial molar volumes of C, B, Si and P in dilute binary solutions at 1823 K are (cm3/mol): 1.59, 3.37, 7.06 and 6.26 respectively. The model correctly describes the liquid alloys of iron with metalloids as interstitial solutions.

铁与C、B、Si、P、Cu、Al、Ni、Cr和Mn液相合金的密度和摩尔体积

本文讨论了含C、B、Si、P、Cu、Al、Ni、Cr、Mn的铁液相合金的密度和摩尔体积。用硬球模型认为铁与其他金属的液态合金是替代溶液。利用多余体积与熵的关系，分析了Fe-Cu和Fe-Al合金的摩尔体积与理想溶液的偏差。铁与Ni、Cr、Mn的合金接近理想溶液。计算体积与实验数据吻合较好。采用P. Gaskell的过渡金属与类金属非晶态合金模型，将含C、B、Si和P的Fe合金视为间隙溶液。在1823 K时，C、B、Si和P在稀二元溶液中的偏摩尔体积分别为(cm3/mol): 1.59、3.37、7.06和6.26。该模型正确地将含类金属的液态铁合金描述为间隙溶液。

期刊介绍： High Temperatures – High Pressures (HTHP) is an international journal publishing original peer-reviewed papers devoted to experimental and theoretical studies on thermophysical properties of matter, as well as experimental and modelling solutions for applications where control of thermophysical properties is critical, e.g. additive manufacturing. These studies deal with thermodynamic, thermal, and mechanical behaviour of materials, including transport and radiative properties. The journal provides a platform for disseminating knowledge of thermophysical properties, their measurement, their applications, equipment and techniques. HTHP covers the thermophysical properties of gases, liquids, and solids at all temperatures and under all physical conditions, with special emphasis on matter and applications under extreme conditions, e.g. high temperatures and high pressures. Additionally, HTHP publishes authoritative reviews of advances in thermophysics research, critical compilations of existing data, new technology, and industrial applications, plus book reviews.
