Abstract

The aluminum–boron–nitrogen phase diagram is calculated at a pressure from 0.1 MPa to 9 GPa by the models of phenomenological thermodynamics in the Thermo-Calc software package with interaction parameters from literature data and equation of states for competing phases. The comparison of our calculation results with the experimental studies of the phase composition of polycrystalline boron nitride samples sintered ay high pressures and temperatures shows their agreement.

压力高达 9 GPa 时 Al-B-N 相图的热力学计算

摘要通过 Thermo-Calc 软件包中的现象热力学模型，利用文献数据中的相互作用参数和竞争相的状态方程，计算了 0.1 MPa 至 9 GPa 压力下的铝-硼-氮相图。将我们的计算结果与在高压和高温下烧结的多晶氮化硼样品相组成的实验研究结果进行比较，结果表明两者是一致的。

期刊介绍： Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
