Abstract

Using an explosive welding technique, aluminum plate was welded onto various metallic plates and the interfacial reaction phenomena are discussed. Normally, the interfacial zone showed a high-aluminum content phase which dissolved a small amount of the component of the welded material. It was assumed that an intensive deformation at the collision point was mainly generated within the aluminum. In the case of Al-Ti, the aluminum content was decreased and the composition corresponded with TiAl or Ti₃Al which suggested that the mechanism of the reaction was changed.
