人们现己认识到,超塑性是陶瓷的一种潜在的变形过程。这篇评述总结了起塑性的主要特征,并分析了陶瓷相变超塑性与结构超塑性的研究报告。分析表明,它与金属既存在相同之处,也存在不同之处。相同之处包括应变率随应力和晶粒大小而变化,而重要的区别是必须考虑陶瓷中间玻璃相的作用。 It has now been recognized that superplasticity is a potential deformation of ceramics. This review summarizes the main features of plasticity and analyzes studies on the phase transition superplasticity and structural superplasticity of ceramics. Analysis shows that it has both the same metal, but also there are differences. Similarities include strain rates that vary with stress and grain size, and the important difference is that the ceramic intermediate glass phase must be considered.
