Microstructure of Joints Processed by Ultrasonic Consolidation of Nickel Sheets

Metals, 2022
Ultrasonic consolidation is an advanced process of sequential solid-state joining of metal foils or sheets by ultrasonic welding. This process was used for joining six sheets of nickel with a thickness of 0.2 mm.

Advances in Superplasticity from a Laboratory Curiosity to the Development of a Superplastic Forming Industry

Metals, 2022
Superplasticity refers to the ability of some materials to pull out to tensile elongations of 400% or more when the strain rate sensitivity is ~0.5. The first report of true superplastic flow was published in 1934 in experiments conducted in England ...

High-Temperature Deformation Behavior of the AZ31 Alloy Processed by Double-Sided FSW Technology

Metals, 2022
Generally, AZ31 magnesium alloys have poor formation ability near room temperature. This material, with ultrafine grains, usually exhibits excellent superplasticity at high temperature.

Low-temperature superplastic deformation of the EK79 nickel-based superalloy with the mixed ultrafine-grained microstructure

Frontier Materials & Technologies
One of the most effective ways to increase the processing plasticity of advanced superalloys (heat-resistant nickel-based alloys) is the formation of an ultrafine-grained (UFG) microstructure in bulk semi-finished products.
