This study explores the explosive welding of titanium (Grade 2 Ti) and
aluminum (Al5083–H111) alloys at varying detonation ratios (R = 1.5, 2,
2.5, 3). Following the welding process, mechanical and metallurgical
tests, including micro hardness, tensile-shear, and bending tests, were
conducted, and performance was assessed through SEM imaging for
microstructural analysis. Ballistic tests were also performed to
evaluate the suitability of the welded materials for specific
operational conditions. The explosive welding process induces
high-velocity impact, causing mechanical interlocking at the interface.
As the detonation ratio increases, the interface waviness and mechanical
bonding improve. At R = 3, significant increases in hardness were
observed in both the titanium and aluminum plates. Tensile-shear tests
showed no fractures or separations at the bonding interfaces, with
titanium's tensile strength increasing as the detonation ratio rose. No
intermetallic formation occurred, and the wavy interface ensured
mechanical interlocking. Bending tests revealed no failures,
demonstrating the process's reliability. Microstructural analysis
confirmed the absence of intermetallics, and all tests met ASTM A
263-94a standards. In conclusion, with appropriate detonation ratios and
parameters, titanium-aluminum joints can be effectively and reliably
produced through explosive welding.
