Notes:
As TiAl based alloys begin to approach maturity, the development of successful and costeffective joining methods will be required. The growing industrial interest in these materials,particularly in aerospace and automotive industry, led to an interesting challenge - how to joint partsand components in order to produce integrated and resistant structures. Diffusion bonding ofmaterials produces components with thinner interfaces than other joining techniques do. Theabsence of abrupt microstructure discontinuity and the small deformation induced maximize jointstrength.This work focuses on the joining of TiAl using a thin multilayer obtained by alternating nanometriclayers of titanium and aluminium. The Ti/Al layers were deposited onto the γ-TiAl samples by DCmagnetron sputtering. The interfaces of these diffusion bonded joints depend on processing anddeposition conditions. In this work we describe the influence of bilayer thickness (period) and onmicrostructure and chemical composition of the joining interfaces
