制备块体纳米材料的新工艺——等径角挤压

Preparing Bulk Nanostructured Materials through Equal Channel Angular Pressing

综述了等径角挤压法制备块体纳米材料的发展及其工艺原理 ,并在此基础上论述了等径角挤压材料的微观结构及其应用 ,指出了等径角挤压法目前存在的问题。

This paper summarizes the present state of preparing bulk nanostructured materials through ECAP ways in common use and the principle. Based on the above the application and microstructure of ECAP materials are discussed. And the existent problem of ECAP is analysed in this paper.
