“…A similar observation of the particles has been reported in [19] where fine iron-rich particles were found in copper with the same morphology. Steward et al [12] also suggested that these particles were iron-rich precipitates mostly being FeCu2 and FeCu18, determined by wavelength-dispersive X-ray spectroscopy. According to the EDS point analysis performed on the star-shaped particles, Fig.…”

“…Guoqing et al [15] used electron beam welding with maximum electron beam gun power of 60 kW, acceleration voltage of 60 kV and beam current intensity that could be adjusted from 0 to 1000 mA for welding-brazing of WC-Co hard alloy to a steel with Ni-Fe intermediate. Steward et al [16] studied furnace brazing of stainless steel (304) to vanadium alloy (V-5Cr-5Ti) with pure copper filler metal. Laser brazing of a steel/aluminum assembly with hot filler wire (88 % Al, 12 % Si) was studied by Mathieu et al [17].…”

In the present study, laser brazing of austenitic stainless steel (type 321) and martensitic stainless steel (type 410) have been performed using 400 W pulsed Nd:YAG laser with silverbased filler metal. The microstructure was investigated using Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Spectroscopy (EDS). The laser brazed joints consist of α-Ag solid solution, α-Cu solid solution surrounded by the α-Ag solid solution and eutectic structure. Filler metal shows better spreading on 321 stainless steel because of more content of Ni and presence of Ti as an activator in the alloy. The average thickness of reaction layer is approximately 3.2 µm for 321 stainless steel and 2.2 µm for 410 stainless steel. The tensile strength of 321 stainless steel joints is higher than that of 410 stainless steel joints due to higher thickness of reaction layer, more spreading and smaller wetting angle. The average of micro hardness for joints in a seam is approximately 146 HV. K e y w o r d s : plaser brazing, 321 stainless steel, 410 stainless steel, silver-based filler metal,

“…For example, type 304 stainless steel was brazed to vanadium alloy in a high-vacuum furnace by using an electron beam, in which the vessel had a pressure of 10 24 -10 25 Pa and the brazing cycle was about 3 h or more. 7 Moreover, the traditional vacuum brazing employs resistance's radiation heating, induction heating method and so on. The radiation heating efficiency is low as a result of lack of conduction or convection inside the chamber, resulting in low heating speed during the vacuum brazing process.…”

A novel vacuum brazing technique, termed glow discharge plasma brazing, is investigated. During the brazing process, the heating temperature of base metals is proportional to the square of the operating barometric pressure and the operating voltage, and the temperature distribution of the base metals is easily regulated by means of suitable measures. The ion beam from the glow discharge anode can efficiently sputterclean the surface of the base metals and the filler metal, which improves the wetting and spreading properties of the filler metal. Unlike the traditional vacuum brazing process, a high quality braze of Fe-Ni alloy is achieved at lower vacuum (a pressure of 5-30 Pa or higher) by using the glow discharge brazing method. The brazing technique has a promising application in industry.STWJ/439
