| 英文摘要 | Continuous carbon fiber reinforced lithium aluminosilicate glass ceramics matrix composites (Cf/LAS composites) are joined to Ti60 alloy vacuum brazed using Ti-Zr-Ni-Cu brazing alloy. The effects of the brazing temperature on the interfacial microstructure and mechanical properties of brazed joints are investigated in details. The interfacial microstructure varies apparently with an increase of the brazing temperature. The thicknesses of the banded Ti solid solution (Ti(s, s)) and the reactive layer between Cf/LAS composites and the interlayer grow gradually. The mechanical properties of brazed joints increase firstly and then decrease with an increasing temperature. In addition, a joint that is brazed at 980 °C for 10 min shows the highest shear strength of ∼38.13 MPa. At the same time, the fracture paths of brazed joints also change as the temperature increases. When the brazing temperature is 950 °C, the fracture position is in the TiC + ZrC + Ti2O + ZrSi2 + Ti5Si3 layer on the composite side. When the brazing temperature is 980 °C, the fracture position is on the side of the braze seam (Ti, Zr)2(Ni, Cu), Ti2O + ZrSi2 + Ti5Si3 layer, and carbon fiber in the composite material. When the brazing temperature is 990 °C, the fracture position is in the Ti2O + ZrSi2 + Ti5Si3 layer on the composite side and the carbon fiber in the composite material. © 2018 Chinese Society of Aeronautics and Astronautics |
