Explosive welding of a thin magnesium plate onto some metal plates was performed by using underwater explosive welding technique developed by some of the authors. The experimental results show that the wavy interface which is typically found in the well-bonded clad was observed. The welding condition is discussed using the welding window based on the numerically simulated results using AUTODYN-2D code.

Using an adjusted explosive welding technique, a Zr-2 alloy plate, a titanium plate and a carbon steel plate were cladded to form a three-layer composite panel which is difficult to manufacture by common methods. Microstructural evaluations reveal that a metallurgical bonding interface with wave morphology is realized, and the grains near the interface are smaller than grains in other areas. The microhardness of the sample near the interface is greatly higher than that of other areas. Furthermore, mechanical experimental evidence indicates the shearing strength of the interface in the moderate condition exceeds that of the interlayer plate.

The supercritical liquid discovered in 1821, the specific character was known for many years. However, it began to be used industrially in Japan after the oil shock of the second half of the 1970s. Development of the process which extracts the high ingredient of added value focusing on fields, such as food and medical supplies, using the super-criticality CO2 was furthered at first in Germany. The supercritical water attracts attention with a rise of the concern of the latest resources problem or an environmental problem. Moreover, the process development such as recycling, decomposition of dioxin and PCB and oilizing and monomerizing of a waste plastic have been active. In recent years, use of the woody biomass is briskly performed on Europe. Since there is the woody biomass abundantly, it tends to go into a hand. In this paper, the supercritical liquid is described briefly. Next, the experiment of supercritical treatment of wood is described. And finally, we proposed using the explosive welding technique for the development of pressure vessel and performed the numerical simulation.

In this research, surface modification of copper with molybdenum was made using explosive welding technique. The underwater shock waves derived from the detonation of explosives was used to bond thin films of molybdenum on copper. Visual observation shows a sound joining of Mo/Cu. Microstructural characterization reveals the bonding interface with a clear wave formation between the participant metals. A clear wavy interface is formed when the weldable conditions lie in the weldability window. When the weldable conditions lie near the right limit or lower limit, a jet trapped region was formed.
