Title: Diffusion vacuum brazing of TiAl47 casting alloy based on TiAl (γ) intermetallic compound using Ag-Cu-Ti braze alloy
Author: M. ROZANSKI, A. WINIOWSKI

Abstract: The basic physical and chemical properties of titanium aluminide alloy based on intermetallic phase TiAl (γ) as well as its brazeability have been discussed. The principles of the diffusion brazing process and application conditions have been presented. The shear strength and structures of the joints of TiAl47 alloy based on the TiAl (γ) phase diffusion brazed with the use of 63Ag-35.3Cu-1.75Ti alloy interlayers as well as brazing conditions have been given. The structural tests were conduced using light microscopy, scanning electron microscopy (SEM) and energy – dispersion spectrometer (EDS). The results of shear strength tests and microhardness tests were also presented.
