摘要：

In this study, a commercially available Ag-Cu-Ti braze alloy foil was used to join SiO2 glass ceramic and 30Cr3 high-tensile steel. According to experimental observations, the interface structure can be expressed as SiO2 glass ceramic/TiSi2+Ti4O7/Ti2Cu+Cu3Ti3O/Ag(s.s)+Cu(s.s)/TiFe2/30Cr3 high-tensile from SiO2 glass ceramic side to 30Cr3 high-tensile steel side. With the increased brazing temperature, the thickness of Ti2CU+Cu3Ti3O layer increases at first and then reduces. The thickness of TiSi2 +Ti4O7 layer and that of TiFe2 layer rise with the increased brazing temperature. According to experimental results of the mechanical properties, the maximum shear strength is 37 MPa when the joint was brazed at 900 degrees C for 5 min. (C) 2008 Elsevier B.V. All rights reserved.
