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。本项目还旨在揭示陶瓷的超塑性变形机理，并为陶瓷的超塑性成形开发一种新的工业技术。在1996-1998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，建立了超塑性变形机制，并提出了超塑性现象的新概念--“晶界塑性”。我们组织或在几个会议中发挥关键作用，如(1)国际会议PRICM-3特别会议“超塑性和超塑性成形”，(2)“迈向超塑性创新I和II”国际会议或(3)“迈向超塑性创新”公开会议。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关键课题之一。这种方法无疑是突破目前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.
