【摘要】 采用纯Ｔｉ，Ｂ，Ａｌ粉末通过真空热压反应烧结，成功地制备了原位ＴｉＢ_２增强的Ｔｉ_ｘＡｌ_ｙ金属间化合物基复合材料。结果表明，原位生长的ＴｉＢ_２多为尺寸小于０．１μｍ的块状粒子，并在基体中呈现比较明显的偏聚，粒子与基体的界面结合是良好的。更多还原

【Abstract】 n situ TiB2 particulate rein forced TixAly in termetallic compound matrix compo site was successfully fabricated by reaction sinter of pure Ti, B and Alpowders in vacuum.In-situ formed TiB2 with a size of less than 0. 1μm are block-like particulates and segregated obviously in the matrix. The interfacial bond between TiB2 particulate and matrix is good.更多还原
