The microstructures and weldability of a brazed joint of 1Cr18Ni9Ti austenitic stainless steel with BNi-2, BNi82CrSiBFe and BMn50NiCuCrCo filler metals in vacuum were investigated. It can be observed that an interdiffusion region existed between the filler metal and the base metal for the brazed joint of Ni-based filler metals. The width of the interdiffusion region was about 10 μm, and the mic...

in the present study, the corrosion behavior of aisi 347 austenitic stainless steel to astm a335 low alloysteel dissimilar joint was investigated. for this purpose, two filler metals, er309l and ernicr-3, were selected to be used during the gas tungsten arc welding process. to investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solut...

The flexural strength and flexural modulus of an experimental metal-resin composite, which used Ag-In alloy particle as the filler, were evaluated. The effect of acid treatment and heat treatment on the Ag-In alloy particle was investigated. The flexural strength of the experimental metal-resin composites ranged from 65.5 MPa to 91.0 MPa. The flexural strength of the metal-resin composite incre...

In hybrid laser–MIG keyhole welding, anti-crack elements can be added into the weld pool through a filler metal in anticipation of compensating mass loss, preventing porosity formation and improving compositional and mechanical properties of the welds. Understanding the mixing and diffusion of the filler metal in the molten pool is vital to achieve these desired objectives. In this study, mathe...

The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...
