颗粒增强复合材料超塑性中颗粒作用的研究

Study on the Effect of Particle on Superplasticity of Particle Reinforced Composites

本文介绍了颗粒增强复合材料超塑性中颗粒的作用：与基体材料相比超塑行为被改变；有利于形核及阻碍晶粒长大；可省去固溶与过时效预处理工序。

This paper reveals the effects of particle on superplasticity ofparticle reinforced composites. The addition of particle into matrix alloychanged the superplastic behavior of the alloy. It promotes the nucleation andobstructs the growth of grains. There is no need for solid solution and overaging pretreatments in the superplastic deformation process.
