Microstructure and Mechanical Properties of TiB-Ti/Ti-6Al-4V Composites Fabricated by Spark Plasma Sintering

摘要：

　　TiB-Ti/Ti-6A1-4V composites were fabricated by spark plasma sintering (SPS) technique under a pressure of 50MPa, with sintering temperature of 1300 ℃ and heating rate of 100 ℃/min.The effect of the TiB content in TiB-Ti composite layer on microstructures and mechanical properties of the TiB-Ti/Ti-6A1-4V composites were investigated.The results indicate that as an advanced welding method, SPS technique provided the excellent welding combination of TiB-Ti and Ti-6Al-4V.The relatively excellent mechanical properties of the joints, including the relative density of 98.6%, micro-hardness of 10.2GPa, fracture strength of 177MPa were achieved as TiB content in TiB-Ti composite layer reaches 50%.
