High Temperature Performance of 316L-SS Joint Produced by Diffusion Bonding

Abstract:

Two types of joining specimens with and without Ni foil interlayer between 316L–SS bar have been prepared by diffusion bonding in a temperature range of 850- 1050°C, under a uniaxial pressure of 10MPa for 1hours. The relationship between the bonding parameters and the tensile strength of the joints at elevated temperature was studied. Optimized processing parameters were suggested based on the testing results. It was found that the introduction of the interlayer may reduce the room temperature strength but increase the high temperature strength. This was attributed to the transformation of Fe0.64Ni0.36 formed in bonding process into FeNi3 at high temperature.

Effect of Interlayer Thickness on Strength and Fracture of Si₃N₄ and Inconel600 Joint

Authors: Min Yang, Zeng Da Zou, Si Li Song, Xin Hong Wang

Abstract: In this study, Si3N4 was bonded to Inconel600 with Nb/Cu/Ni interlayer by partial liquid phase diffusion bonding method under vacuum condition. The bonding temperature, bonding time, bonding pressure and cooling velocity was 1403K, 50min, 7.5MPa and 5K/min, respectively. The effects of interlayer thickness on the strength and fracture behaviors of joint were investigated through evaluating the strength of joints based on shear test and observing the fracture morphology by means of SEM. The results showed that the shear strength of joint changed with variation of the interlayer thickness. When the shear strength of joint increased, the location of fracture was changed from the ceramic/interlay interface to the reaction layer.

Diffusion Bonding of Al 6061 Alloys Using an Eutectic Reaction of Al-Ag-Cu

Authors: Young Sup Lee, Cheol Ho Lim, C.H. Lee, K.W. Seo, Seung Y. Shin, Chang Hee Lee

Abstract: In this study, a diffusion bonding of aluminium alloy A6061 was preformed using an Ag-28Cu filler metal in order to conduct eutectic brazing. Melting mechanism was surveyed. Interface behaviors of the brazed joints were observed after brazing and T6 solution treatment. Also, tensile property of the brazed joints was examined. During diffusion bonding of Al6061 alloys with Ag-28Cu filler metal, eutectic melts were formed by eutectic reaction between Al6061 and Ag-28Cu filler metal. It was found that the reaction layer consist of two phases formed at the interface between AA6061 and Ag-28Cu filler metal. EPMA analysis revealed that two phases in the reaction layers consist of Ag-rich phase and Cu-rich phase. Tensile strength was 300 MPa after ageing treatment at 175°C.

Authors: Yasushi Fukuzawa, Shigeru Nagasawa, Masahiro Watanabe, Shigehiko Takaoka

Abstract: To develop the new bonding method under low bonding temperature and short holding duration, pulse electric current sintering (PECS) method is applied. The Ni plating layer was used as the interlayer. The following experimental factors were researched:(1) Thickness of Ni plating layer, (2) Bonding temperature, (3) Bonding pressure and (4) Heat treatment after plating. The bonding strength of W-Ni plate-Cu joint could be obtained under low bonding temperature of 773 K and short bonding duration of 10 min.

Interfacial Microstructure and Strength of Vacuum Brazed Joints of Ternary Ceramics Ti₃SiC₂

Authors: Li Ping Shi, Ye Sheng Zhong, Jia Yu, Xiao Dong He

Abstract: Ti3SiC2 is one of the nano-layered ternary ceramics Mn+1AXn, where M is a transition metal, A is an A-group (mostly IIIA or IVA) element, and X is C or N. With the filler of Ag-Cu-Ti, the brazing of Ti3SiC2 has been conducted at 800°C–950°C for 5-10min under 3.5×103Pa in a vacuum. The phase composition and microstructure of the joints were investigated by XRD, SEM AND EPMA. The diffusion of Cu element in fillers through the reaction zone toward Ti3SiC2 is the main controlling step in the bonding process. Joint strengths were evaluated by three point bending test. The maximum flexural strength of joints reaches is 306±11MPa, which is lower than the bending strength of Ti3SiC2, obtained under the same condition.

A Study on Weldability of Aluminum Alloy-Aluminum-Steel Transition Joints

Authors: Jian Min Wang, Yan Zhang

Abstract: Aluminum alloy-aluminum-steel cladding plates were manufactured by explosive welding. Microstructures of the cladding plates were observed and the interface bonding properties were tested. Aluminum alloy-aluminum-steel transition joints were produced by welding the explosive cladding plates. The bonding interface configuration and property were investigated and tested after welding. The effects of welding technology on the interface bonding properties were discussed. The results showed that metallurgical behavior has been occurred at the bonding interfaces between aluminum alloy and aluminum and aluminum and steel. Regular sine waves have appeared on the bonding interface between aluminum alloy and aluminum. However, the bonding interfaces between aluminum and steel present line-shape. The shear strength and separate strength of the cladding plates were much higher than the standard strength. After being welded, the configuration of the bonding interface has no marked change. The strength of the bonding interface decrease a little. The welding technology had no remarkable effect on the bonding interface of the aluminum alloy-aluminum-steel cladding plates.
