Effect of bonding time on microstructure and mechanical properties during TLP bonding of nickel-base superalloys Hastelloy C276 and Stainless Steel AISI316
Joining of Hastelloy C276 nickel-base superalloy to AISI316 Stainless Steel using BNi-2 interlayer performed by transient liquid phase process (TLP) at 1150°C for 5 and 30 minutes. Bonding microstructure was studied using an Optical microscope and a scanning electron microscope (SEM). Vickers hardness test and shear strength test have been used to evaluate the mechanical properties. Microstruct...

متن کاملMicrostructural Modeling During Multi-Pass Rolling of a Nickel-Base Superalloy
Superalloys are metallic alloys used for high temperature applications such as encountered in the aircraft industry and where resistance to deformation is a primary requirement. Alloy 718 and waspaloy are few examples of Nickel-base superalloys that resist deformation at elevated temperatures and are therefore difficult to hot work. The major hotworking operations are forging, extrusion, and ro...
متن کاملReview on Thermo-Mechanical Fatigue Behavior of Nickel-Base Superalloys
Nickel-base superalloys have become the key materials of hot-end components in the aeroengines over the past several decades. Nickelbase superalloys are easy to produce thermo-mechanical fatigue (TMF) behavior when withstanding the combined effects of high temperature, creep, oxidation, mechanical stress and thermal stress. The occurrence of TMF seriously affects the normal service for hot-end ...
متن کاملResidual Stress Assessment in Surface-treated Nickel-base Superalloys
Experimental results are presented to illustrate that there exists a unique window of opportunity for eddy current NDE of residual stress in surface-treated nickel-base superalloys. In light of its frequency-dependent penetration depth, the measurement of eddy current conductivity has been suggested as a possible means to allow the nondestructive evaluation of subsurface residual stresses in su...
