| 摘 要： | 研究了强电场对１５ｖｏｌ％ＳｉＣｐ／ＬＹ１２复合材料超塑性变形的影响。结果表明，合适的强电场可提高应变速率敏感性指数ｍ值，降低流动应力、提高极限延伸率，细化晶粒。因此，电场改善了ＳｉＣｐ－Ａｌ复合材料的超塑性能。

| Abstract: | Effects of electric field on superplastic deformation of SiCp/LY1 2 Al composite HAVE BEEN INVESTIGAT-ed. The resuLts show that the application of an appropriate electic field increases the strain -rate sensitivity exponent,decreases the flow stress,elevates the limit elongation and fines the size of grains ,So it believed that the electricfield improven the superplasticity of SiCp - Al composte. |
