摘      要：Dissimilar joints(DSJs)of ferrous and non-ferrous metals have huge technological importance in the frontiers of newdesigns in new machineries and improved design of conventional *** investigation was undertaken to improve mechanicalproperties of joints of two dissimilar metals:one is Ti-based and the other is *** were processed using bonding pressurefrom1to9MPa in step of2MPa at750°C *** of the DSJs of these two metals using different mechanisms andmethods were compared with the present research for *** results from the diffusion bonding mechanism forjoining the dissimilar metals validated the improvement in *** mechanical properties of dissimilar-metals joints wereachieved mainly due to the third non-ferrous metallic foil,Ni of^200-?m thickness,which avoided the formation of brittleFe-Ti-based intermetallics in the diffusion *** processed are able to achieve maximum strength of^560MPa along withsubstantial ductility of^11.9%,which is the best ever reported in the literatures so *** hardening effect was detected in theDSJs when the bonding was processed at5MPa and *** ratio of the non-ferrous metal(Ti-based)was much higher thanthat of the ferrous metal(SS)of the DSJs *** analysis was carried out to know the details of reaction zone,while XRDwas carried out to support the SEM *** for change in mechanical,physical,and fracture properties of the DSJs with theprocess parameter variations were clarified.
