| Abstract Scope |
Explosive welding is a solid-state bonding technique that preserves the mechanical integrity of base metals while enabling the formation of high-strength joints. The mechanical behavior of explosively welded dissimilar metal systems strongly depends on the quality of the bond interface. This study investigates the mechanical response of bonded specimens through compression testing coupled with digital image correlation (DIC) to map strain fields across the joint. DIC revealed unique deformation patterns that highlight the potential of this technique for evaluating interfacial strength. Additionally, nanoindentation measurements across the bonded region provided localized hardness and modulus values, emphasizing phase-specific mechanical behavior. Complementary electron backscatter diffraction (EBSD) analysis identified variations in deformation and microstructural evolution across the interface. This integrated characterization approach offers critical insights into the relationship between interfacial structure and mechanical performance, contributing to a better understanding of the long-term reliability of explosively welded systems. |
