摘要：

Spark plasma assisted resistant heating process is an emerging technique for joining materials in a short duration. In this paper, diffusion bonding of Inconel 718 alloy was carried out by spark plasma sintering (SPS) at a temperature of 850 degrees C (Heating rate of 50 degrees C/min) with the pressure of 50 MPa and holding time of 5 min. The diffusion bonded samples were solutionized and double aged. Microstructural analysis of bonded samples was analyzed through an optical microscope. The mechanical tests such as hardness and tensile tests were carried out to understand the strength of the diffusion bonded samples at various conditions. The corrosion behavior of samples was studied and analzysed. (C) 2019 Elsevier Ltd. All rights reserved.
