Superplasticity in Ceramics

“陶瓷中的超塑性”项目旨在研究精细陶瓷材料中的超塑性现象。本项目旨在揭示陶瓷的超塑性变形机理，开发一种新型的陶瓷超塑性成形工业技术。在1996年至1998年的研究期间，我们成功地揭示了晶界对陶瓷超塑性的作用，建立了超塑性变形的机理，并从“晶界塑性”这一超塑性现象的新概念方面进行了研究。我们组织或在多个会议中发挥关键作用，如(1)国际会议PRICM-3“超塑性和超塑性成形”专题会议，(2)国际会议“超塑性创新I和II”或(3)公开会议“超塑性创新”。从晶界微观结构的角度研究超塑性现象是我们研究结果的一个重点。这种方法无疑是突破先进材料超塑性研究现状的最有效途径之一。

The project "Superplasticity in Ceramics" aims to examine superplastic phenomena in fine-ceramic material. This project also aims to reveal a mechanism of superplastic deformation in ceramics, and to develop a new industrial technology for superplastic forming of ceramics. During the research term from 1996 to 1998, we succeed in revealing role of grain boundary for the superplasticity in ceramics, establishing the mechanisms of superplastic deformation and in terms of "grain boundary plasticity", which is a new concept for superplastic phenomena. We organize or make a key role in several conference and meetings, such as (1) International Conference PRICM-3 special session "Superplasticity and Superplastic forming", (2) International Conference on "Towards Innovation in Superplasticity I and II" or (3) Open meeting "Towards Innovation in Superplasticity". One of our key topics of out results is to examine the superplastic phenomena from the viewpoint of microstructure in grain boundary. This type of approach is no doubt one of the most effective ways to break through the present situation in superplastic research in advanced materials.
