| 摘 要： | 对ＳＨＳ／ＰＨＩＰ技术制备出的ＴＩＣ－Ａ１２Ｏ３－Ｆｅ复合材料的微观组织结构进行了分析和研究．结果表明，随着Ｆｅ含量的增加，ＴＩＣ颗粒尺寸减小，Ａｌ２Ｏ３的分布趋于均匀．在ＴｉＣ晶粒中发现少量颗粒相；在Ｆｅ粘结相中发现具有ε－ＡｌＦｅ３Ｃ０．６９型结构的胞状相；ＴｉＣ晶粒中存在大量位错．

| Abstract: | The microstructure of TiC-Al2O3-Fe composites prepared by SHS/PHIP was studied. As the Fe content was increased, the particle size of TiC decreased, and the distribution of Al2O3 became homogeneous. There existed a little of particle phase in TiC grains. While some of ε-(AlTi)Fe3Cx cellular phase with ε-AlFe3C0.69 structure was found in Fe-binder phase. A great deal of dislocation were observed in TiC grains because of the rapid pressing in the process of SHS/PHIP. |
