Explosive Cladding and Hot Pressing of Ti/Al/Ti Laminates

Ti/Al/Ti laminates were prepared by an explosive cladding method. Then hot pressing was employed to further process the laminates. The results indicate that both linear and wavy bonding interfaces coexist and element diffusion occurs in the interfacial zone between the titanium and aluminum layers after explosive cladding. After 25 h heat treatment and 2.5 h hot pressing, the aluminum layer is consumed completely. The reaction layer consists of Al3Ti and Ti2Al5 phase.
