Brazing continuous carbon fiber reinforced Li2O-Al2O3-SiO2 ceramic matrix composites to Ti-6Al-4V alloy using Ag-Cu-Ti active filler metal

Brazing of continuous carbon fiber reinforced Li2O-Al2O3-SiO2 ceramic matrix composites (Cf/LAS composites) to Ti-6A1-4V (TC4) alloy was achieved with AgCuTi filler metal. (a) The microstructures of Cf/LAS composites. (b) Interfacial microstructure of TC4/AgCuTi/Cf/LAS composites joint brazed at 890 °C for 10 min. (c) Interfacial microstructure of carbon fiber/AgCuTi interface of TC4/AgCuTi/carbon fiber joint brazed at 890 °C for 10 min. (d) Effect of brazing temperature on the shear strength of TC4/AgCuTi/Cf/LAS composites joints.
