The use of filler materials during fusion-based welding processes is widely used to regulate
and modify the composition of the welded joints aiming at producing a desired …

In this work, dissimilar laser welding between an as-rolled CoCrFeMnNi high entropy alloy
(HEA) and Inconel 718 Ni-base superalloy was successfully performed. Defect-free joints …

We investigated ultrasonic welding (USW) of pure α-Ti sheets, which exhibited an
insufficient weldability due to the extensive formation of cracks caused by sliding friction …

Medium-and high-entropy alloys (MEAs/HEAs) or multi-principal element alloys are a new
class of promising alloys with wide application possibilities in several industries like nuclear …

Vacuum hot-compression bonding (VHCB) is a highly competitive solid-state bonding
technology. To expand the application prospects of VHCB in high-entropy alloys (HEAs), the …

This study investigated the role of interfacial deformability in bond integrity and strength,
particularly in the production of robust joints between harder austenitic stainless steels (SS) …

In this study, the effect of bonding surface conditions on the strength evolution of Cu/Cu
joints during ultrasonic welding was investigated. Lap shear tests and microstructure …

Ultrasonic spot welding (USW) was employed to join AA7075-T6 and casting Al alloy A380.
Under a constant welding power, the influence of the welding time duration (from 1 s to 3 s) …

Ultrasonic spot welding, as a high strain rate plastic deformation process, utilizes the high
frequency sliding between the metal sheets to generate a solid-state joining. For the …

Vacuum hot-compression bonding (VHCB) is a promising solid-phase bonding technology,
but its feasibility and applicability in high entropy alloy (HEA) are still unclear. Herein, the …
