| 摘 要： | 得到广泛应用的结构陶瓷的另一特点是塑性差,难以进行塑性加工.因此对其超塑性的研究便成为国内外竞相研发的热点之一.针对Y2O3部分稳定四方ZrO2(Y-TZP),Al2O3,Si3N4和SiC等结构陶瓷,分别就其拉伸(压缩)宏观力学实验.微观物理机理、晶体结构和添加物对超塑变形的影响,以及对其进行的力学测量结果和研究进展进行了综述.

| Abstract: | Other character of the structural ceramics is very low plasticity, resulting in especially hard to form complicate and large--scale parts. The research of the superplasticity of structural ceramics is one of the hotspots in the world. As examples, Y-TZP, Al2O3, Si3N4 and SiC were analyzed and the content emphasizes on tensile (compress) mechanical tests, microscopic mechanism and effects of crystal structure and additions on structural ceramics' superplastic deforming. In addition, its mechanical measurements and advanced research were also overviewed. |
