SiCf/Ti基复合材料基体织构的EBSD研究

Studies on Texture in Matrix of SiCf/Ti Composite by EBSD

摘要:

利用电子背散射衍射技术(EBSD)研究了箔-纤维-箔法和纤维涂层法这两种制备方法对SiCf/Ti复合材料基体织构的影响。结果表明，箔-纤维-箔法制备的SiCf/Ti-6Al-4V复合材料中基体钛合金的不同区域有不同的织构类型。纤维涂层法制备的SiCf/Super α2复合材料基体中的织构为纤维织构，这正符合复合材料各向异性的特征，为复合材料获得较好的力学性能提供了可能。

Abstract:

The effects of two fabrication methods, foil-fiber-foil (FFF) and matrix coated fiber (MCF), on the texture in the matrix of SiCf/Ti composites were investigated by electron back-scatter diffraction (EBSD). The results show that the texture is different between different zones in the matrix of SiCf/Ti-6Al-4V composite fabricated by FFF. However, there is some fiber texture in the matrix of SiCf/Super α2 composite fabricated by MCF, which is in accordance with the characteristic of anisotropy for composites. This will be beneficial to obtain the high performance composite.
