Effect of interlayer on microstructure and mechanical properties of NiTi/TC4 dissimilar metal resistance spot welded joints

Puntos clave

• Mechanical properties of NiTi/TC4 welded joints vary significantly with the presence of an interlayer.
• The study shows that optimal interlayer configurations enhance joint microstructure, strength, and ductility.
• Dissimilar metal resistance spot welding was used to fabricate the joints and assess their characteristics.
• Understanding these interactions can lead to improved welding techniques for advanced materials.
