本文是对烧结研究的历史和现状的简要评述。有理由将烧结研究的发展史划分为三个阶段。重点论述了烧结理论的创立及其现在的发展。详细描述和讨论了有关烧结过程物质迁移机构的各种研究工作,它们包括粘性流动,蒸发凝聚,体积、表面和晶介扩散以及塑性流动。然而,修正过的一些烧结理论是论述那些称作联合烧结机构的,其中特别报导了黄培云提出的综合作用理论。考虑了烧结的发生是扩散、流动和物理一化学反应的联合作用,能导出一个lnln dm=d0/dm-d对1/T的线性方程,其中d0和dm是烧结开始和终了时粉末压制试样的密度,d是在给定时间和绝对温度T经过等温烧结后的瞬时密度。
This article is a brief review of the history and current status of sinter research. It is reasonable to divide the history of sinter research into three stages. It focuses on the establishment of sintering theory and its current development. Various studies on material transport mechanisms for sintering processes have been described and discussed in detail. These include viscous flow, evaporative coalescence, volumetric, surface and intergranular diffusion, and plastic flow. However, some of the modified sintering theories deal with those that are called co-sintered mechanisms, with particular reference to the synthetic theory of action proposed by Huang Peiyun. Considering that sintering takes place in combination with diffusion, flow and physical-chemical reactions, a linear equation of lnln dm = d0 / dm-d to 1 / T can be derived, where d0 and dm are the powder compacting tests at the beginning and the end of sintering Like density, d is the instantaneous density after isothermal sintering at a given time and absolute temperature T.
