XDTM法制备TiCp/ZA-12复合材料

采用XD^TM法制备TiCp／ZA一12复合材料。组织观察表明：TiCp原位自生，在基体中均匀分布，没有颗粒的偏聚和宏观、微观偏析存在；自生的TiCp多呈近球形，其表面光滑圆整，没有棱角和尖角；与基体合金的界面结合较为紧密，无反应产物存在。拉伸试验表明：复合材料具有较高的抗拉强度和屈服强度。

TiCp/ZA-12 Composites Prepared by XDTM Process

TiCp/ZA-12 composites are prepared by XDTM process.The observed results indicate that TiC particles are formed in-situ and distributed uniformly in matrix. No particles aggregation and macro or micro precipitation are observed . Most TiC particles formed in-situ are almost spherical and present smooth surface. TEM results demonstrate that the interface between TiC particle and matrix is in close bond and no reaction products exist.Tensile tests indicate that the composites exhibit high tensile and yield strengths.
