摘要

对碳化硼基粉末混合物在闪压烧结下的致密化进行了建模。为此开发的计算机模型基于 Skorokhod-Olevsky-Shtern 多孔材料致密化理论，并考虑了烧结过程中的晶粒生长动力学。模型参数是根据实验室和计算实验的结果确定的。通过与现有实验数据的比较，确认了模型的适当性。

Modeling the Densification of Boron Carbide Based Ceramic Materials under Flash Pressure Sintering

The densification of boron carbide based powder mixtures under flash pressure sintering was modeled. The computer model developed for this purpose was based on the Skorokhod–Olevsky–Shtern porous material densification theory and takes into account the grain growth kinetics under sintering. The model parameters were determined from the results of laboratory and computational experiments. Model adequacy was confirmed by comparison with available experimental data.

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.
