采用FAPAS法制备AlMgB14预反应粉,将其与TiB2粉混合,在烧结温度1500℃,轴向压力60 MPa,升温速度100℃/min、保温时间15 min条件下制备了具有较理想组织结构的AlMgB14-30wt％TiB2复合材料.通过HRTEM、SEM和EDS对AlMgB14-30wt％TiB2的微观结构进行表征,研究结果表明:AlMgB 14-30wt％TiB2复合材料的显微硬度31.5 GPa,断裂韧性K1C值可达到3.65 MPa·m1/2,与机械合金化/单轴热压法制备的结果一致.并从微观结构分析了AlMgB14-TiB2复合材料的增韧机制主要来源于TiB2增强相与基体间形成高强结合界面.FAPAS法为AlMgB14基复合材料的制备开拓了低成本高效的新途径.
