Evolution of interfacial dislocation network during anisothermal high-temperature creep of a nickel-based superalloy [PDF]
The effect of thermal cycling creep on the dislocation networks at the γ/γ′ interfaces in the MC2 superalloy is investigated. Tensile creep tests were performed under thermal cycling and isothermal conditions at low stress (80 MPa) and high temperature ...

Soldering Si3N4 to Invar42 by a localized heating process
Abstract This study investigates the soldering process for joining silicon nitride (Si3N4), a commonly used ceramic, to Invar42, a low thermal expansion alloy. The focus lies on analyzing interfacial reactions and evaluating the bonding performance of the Si3N4—Invar42 joint.

Synthesis and thermal properties of dense Si─Al─C─N‐based polymer‐derived ceramics
Abstract In the present study, aluminum‐modified preceramic silicon polymers were synthesized via chemical modification of a commercially available organopolysilazane using an aluminum amido complex. The incorporation of aluminum into the polymer structure and its effect on ceramization behavior and processability as well as the thermal and mechanical ...

This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...
