闪速烧结已成为陶瓷烧结、合成和加工的一个有前途的机会。然而，闪速烧结的三个基本问题仍然没有答案：是什么触发了第一阶段的闪速？是什么导致了第二阶段的快速致密化在第三阶段，微观结构是如何演变的？闪速烧结的机理一般用焦耳加热和非平衡缺陷演化来解释。本文以氧化钇稳定氧化锆为例，对闪速烧结机理的最新研究成果和科学认识现状进行了评述。最后，展望了闪速烧结在陶瓷合成和加工中的应用前景。(C)2020 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Flash sintering has emerged as a promising opportunity for ceramic sintering, synthesis and processing. However, three basic questions about flash sintering remain unanswered: what triggers the flash during Stage I? what causes rapid densification during Stage II? How does the microstructure evolve during Stage III? In general, the mechanism of flash sintering is explained by Joule heating and non-equilibrium defect evolution. Herein, the recent findings and status of scientific understanding regarding the mechanism of flash sintering are critically reviewed by taking the example of yttria-stabilized zirconia. Moreover, the potential applications of flash sintering in ceramic synthesis and processing are presented. (C) 2020 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
