Phase transformations and the melting range of the interlayer BNi-3 were investigated by differential scanning calorimetry, which showed three stages of crystallization during heating. There were three exothermic peaks that indicated crystallization in the solid state. The cobalt-based X-45 and FSX-414 superalloys were bonded with interlayer BNi-3 at a constant holding time of 10 min with bonding temperatures of 1010, 1050, 1100, and 1150 °C using a vacuum diffusion brazing process. Examination ...

Dissimilar transient liquid phase (TLP) bonding between stainless steel 310 and Inconel 617 was carried out using a BNi-2 interface layer. TLP joints were fabricated at 1040, 1070 and 1100 °C for a bonding time of 60 min. In addition to microstructural evaluations, the mechanical properties of different TLP joints were also studied. The results indicated that increasing the bonding temperature resulted in decreasing the solidification zones and accelerating the formation of the intermetallic com...

Abstract This research aims to evaluate the effect of weld pitch on the microstructure and properties of St 37/AISI 316 steels friction stir welds. The microstructure and microtexture of the samples were studied by means of electron backscatter diffraction analysis. The mechanical behaviors of the weldments were also investigated by microhardness, shear punch testing, and uniaxial tensile testing. In addition, the corrosion behavior of the welds was also evaluated. It was observed that the weld ...

The aim of this study is to investigate the microstructure and mechanical properties of friction stir welded super duplex stainless steels. In this regard, UNS S32750 steel is joined by friction stir welding (FSW) method. The tool used in this research is made of WC with 16-mm shoulder diameter and 5-mm pin diameter. Microstructural investigations are carried out by optical microscope and scanning electron microscope. In addition, in order to evaluate the mechanical properties, microhardness and...

Abstract null null Cobalt-based X-45 and FSX-414 superalloys with interlayer BNi-9 have been bonded by a transient liquid phase bonding process at a constant temperature of 1150 °C with the holding times of 1, 10, 60, 120, 180 and 240 minutes. Microstructural changes of base metals showed that the conditions of 1150 °C/240 min can be used to joint base metals, in such a way that the primary carbides of M6C and M23C6 are significantly dissolved in the matrix, forming a supersaturated solid soluti...

In this research, transient liquid phase (TLP) bonding method was used to join Al-2%Nanoclay composite, using a Cu interlayer. The samples were bonded for 60 to 240 min at 580 °C. Microstructural evaluations showed that the bond line was widened by increment in holding time due to dissolution of joint zone and base material. However, bond width decreased in 240-min sample due to the completion of isothermal solidification and subsequent homogenization. Phase assessment revealed CuAl2 precipitate...

Microstructure and microtexture of a dual-phase (DP) steel was investigated using the electron backscattered diffraction (EBSD) technique. A DP600 steel was produced by 60% cold-rolling a low carbon steel with an initial ferrite pearlite microstructure followed by intercritical annealing at 720°C for 1 h. Kernel average misorientation map of the DP600 steel showed that the density of geometrically necessary dislocations as well as the local misorientation is higher in the vicinity of ferrite–mar...

The microstructure and corrosion behavior of friction stir (FS) welded API X-60 pipeline steel were investigated. Three FS welds were successfully fabricated under various welding conditions using a tungsten carbide-base tool. It was found that the microstructure and corrosion performance of the welds were strongly affected by welding parameters. A thermal history study of the welds showed that all stir zones heated up to the temperature of the ferrite–austenite region. Electron backscatter diff...

Thin sheets of N155 superalloy with Inconel 718 filler metal were welded using tungsten inert gas (TIG) process with different frequencies of the pulse current system. The present study aims to compare the hot corrosion resistance of the weld metal of samples with different frequencies in 90% Na2SO4-10% NaCl molten salt environment at 950±5 °C. The results of the hot corrosion test indicated that the sample with optimal frequency (240 Hz) could form the alternate protective layers (Cr2O3 and NiO...
