Underwater explosive welding of thin tungsten foils and copper

Microstructural Characteristics and Mechanical Properties of 2205/AZ31B Laminates Fabricated by Explosive Welding

“…Besides, the high-density dislocations near the interface were formed at the interface of metals when the explosion happened [22]. The high-density dislocations would also provide a channel for element diffusion [2,35]. Similar findings were also observed by Wei et al [17] in the friction stir welding of stainless steel to magnesium alloy.…”

Weldability window and the effect of interface morphology on the properties of Al/Cu/Al laminated composites fabricated by explosive welding

“…It is thought that via this jet, surface contaminants are brought to the interface. Generally, the jet comprising thin surface layers of parent and flyer plate is trapped in the vortices leading to formation of intermetallic compounds [39,40]. Both of these depend to impact velocity, V P , and the explosive ratio.…”

Numerical simulation of explosive welding using Smoothed Particle Hydrodynamics method

“…This technique enables to clad very large section of plates in a single operation and allows us to fabricate large scale composite laminates. Until now, many material combinations, including Al-Cu, Ti-steel, Cu-steel, W-Cu and even multi-layers of metals such as Mg-Al-Ti-Cu-Mo have been welded together using this method [3][4][5][6][7]. However, due to its fast welding characteristic, it is difficult to directly observe and measure the process of explosive welding.…”
