Special Issue Information
Dear Colleagues,
Today’s rapidly evolving advanced manufacturing technologies (e.g., additive manufacturing, field-assisted sintering technology) provide diverse innovative solutions for the welding and joining of similar or dissimilar materials. Joining similar materials with advanced techniques makes it possible to realize new structure designs and offer significant performance enhancement. For example, compact heat exchangers made by diffusion welding can achieve high-efficiency heat exchanger designs with microchannels while maintaining structural integrity. Joining dissimilar materials to make multimaterial components that largely revolutionize component design and can offer diverse material properties in a single part to benefit overall performance. In the die casting industry, for example, multimaterial structures consisting of steel and copper alloys can greatly improve production efficiency by combining the excellent thermal conductivity of copper alloys with steel.
Joining similar or dissimilar materials is highly desired in many industries, bringing numerous advantages, such as weight reduction, energy efficiency, and properties improvement. Although new techniques could advance the joining process, challenges still exist, such as porosity at the interface, microstructure inhomogeneity, deformation, and residual stress.
This Special Issue aims to highlight recent findings in the joining of similar or dissimilar materials, both from experimental characterization and numerical modeling. Topics covered in this Special Issue include but are not limited to: welding and joining; new joining techniques and strategies; novel dissimilar materials design; functionally graded materials; hybrid joining techniques; additively manufactured structures; interfacial bonding strength; phases, microstructure, and porosities at the joint; and residual stress modeling and measurement. This Special Issue endeavors to share recent advances and provide future insights in this crucial area.
