Al/TiB₂ particle reinforced composites were processed through aluminothermic reaction process using potassium hexafluorotitanate (K₂TiF₆) and potassium tetrafluoroborate (KBF₄) salts as precursors and Al (A380) alloy as a matrix material, with different processing conditions such as addition time (AT) of precursors (10 min, 20 min, 30 min), holding time of melt (HT) (20 min, 30 min, 40 min) and melt temperature (700 °C, 750 °C, 800 °C, 850 °C). The combined effect of the process parameters of aluminothemic reaction on the formation of TiB₂, size and distribution of TiB₂ particles in the microstructure and the mechanical properties of Al/TiB₂ composite were studied. The formation of TiB₂ particles were confirmed from XRD pattern. The microstructures showed uniform distribution of TiB₂ particle in Al matrix in the processing condition: addition time (20 min), holding time (30 min) and melt temperature (800 °C). The hardness and ultimate tensile strength of composite have improved 57%, 59% respectively in this condition. The resultant properties were correlated to the microstructure and process parameters. Coarser particles were formed at a lower addition time (10 min) and holding time (20 min) of precursors with all the processing temperatures.

以六氟钛酸钾（K ₂ TiF ₆）和四氟硼酸钾（KBF ₄）盐为前体，以Al（A380）合金为基质材料，通过铝热反应工艺加工Al / TiB ₂颗粒增强复合材料。前体时间（AT）（10分钟，20分钟，30分钟），熔体保持时间（HT）（20分钟，30分钟，40分钟）和熔体温度（700°C，750°C，800°C， 850°C）。铝热反应工艺参数对TiB ₂形成，TiB ₂颗粒的尺寸和分布及Al / TiB ₂力学性能的综合影响。复合材料进行了研究。从XRD图确认了TiB ₂颗粒的形成。微观结构表明，在以下条件下，TiB ₂颗粒均匀分布在Al基体中：添加时间（20分钟），保持时间（30分钟）和熔融温度（800℃）。在此条件下，复合材料的硬度和极限拉伸强度分别提高了57％和59％。所得的性能与微观结构和工艺参数相关。在所有加工温度下，均以较低的添加时间（10分钟）和前体保持时间（20分钟）形成了较粗的颗粒。
