摘要：
Effects of TiB2/TiCx ratios on compression properties and abrasive wear resistance of 50 vol.-% (TiB2-TiCx)/Al-Cu composites fabricated via the combustion synthesis (CS) method assisted with hot press from the Al-Ti-B4C system were studied. With decrease in the TiB2/TiCx ratio from 3:1 to 1:3, the shape of TiB2 changed from platelike to clubbed while the size of TiCx particles increased, which directly led to different mechanical properties. The 50 vol.-% (TiB2-TiCx)/Al-Cu composite with the TiB2/TiCx ratio of 2:1 exhibited good compression strength without sacrificing the fracture strain, while the composite possessed the highest abrasive wear resistance when the TiB2/TiCx ratio was 3:1. The appropriate TiB2/TiCx ratio was recommended to be 2:1 in this research.
