The induction brazing of brass to steel using Ag-cu-Zn-Sn filler metal was investigated in this study. The influence of A8 content on the microstructure and properties were analyzed by means of optical microscopy, scanning electron microscopy and electron probe microanalysis. Defect free joint was achieved using Ag- cu-Zn-Sn filler metal. The microstructure of the joint was mainly composed of Ag-based solid solution and cu-based solid solution. The increase of A8 content and the cooling rate both.l.d to the increase of the needle like eutectic structure. The tensile stre.g.h decreased with the increase of Ag content. The tensile stre.g.h at room temperature using Ag25cuZnSn filler metal reached 445 MPa. All fractures using Ag-cu-Zn-Sn filler metal presented ductile characteristic.

The nonequilibrium α2/γ interfacial structures have been studied using the conventional and high-resolution transmission electron microscope. The nonequilibrium γ/γ and α2/γ interfaces are important microstructure features of hot-forged Ti-45Al-8Nb2.5Mn-0.05B alloys. The characteristics of these nonequilibrium interfacial boundaries include the frequent interfacial le.g.s and the deviation from the conventional orientation relationship {111}γ.
