“…It is necessary to connect the titanium and aluminum to form a composite member, which can reduce the quality of the components, but also to a large extent to play the advantages of the two metals. Titanium / aluminum composite structure in aerospace, weapons and equipment, ship machinery and other fields have a wide range of applications, such as the aircraft wing is the titanium alloy and aluminum alloy honeycomb sandwich connection and the formation of the composite structure [3][4][5].…”

Abstract. In this paper, aluminum alloy and titanium as the research object, the resistance spot welding and post-weld heat treatment were conducted to study the Al/Ti interface reaction layer formation and growth characteristics. Besides, the effect of heat treatment temperature on the growth of Al/Ti bonded interface was investigated under the same heat treatment time. The results show that TiAl3 is the only new phase formed during the heat preservation process. At the same holding time, the thickness of the Al/Ti interface reaction layer increases exponentially with the increase of the heat treatment temperature.

“…L.Xu [3] investigated solid-state reactive diffusion between Ti and Al by employing multi-laminated Ti/Al diffusion couples, found that both Ti and Al diffused into each into each other. To eliminate the effects of unavoidable contamination, L.M.Peng [4] fabricated Ti-Al3Ti laminated in vacuum, and indicated that only the intermetallic Al3Ti is formed and the diffusion processes occurring in liquid Al. Shu-ying JIANG and Shi-chun LI [5] fabricated Al−Ti diffusion couples by embedded technology, studied the growth mechanism of Al/Ti IMCs and suggested that the growth interface moves toward the aluminum side.…”

Abstract. Al-Ti diffusion couples prepared by resistance spot welding are annealed at 575°C for different time. The microstructure of the interface area was investigated. The result shows that there is no obvious intermetallic compound in the interface after welding. According to the SEM (scanning electron microscope) images, a continuous reaction layer is generated between Ti and Al matrix, and the thickness of the reaction layer increases with the annealing time goes by. A SEM equipped with energy dispersive X-ray spectroscopy (EDX) is used to identify the compounds of the reaction layer. The phase of the reaction layer is TiAl3, which is a kind of Al/Ti intermetallic compound (IMC).

Nano-indentation is an important technique to determine the Young modulus of multiphase materials where normal tensile tests are not appropriate. In this work, Ti-TiAl3 metallic-intermetallic laminate composites have been fabricated successfully in open atmosphere using commercial purity Al and Ti foils with 250 µm and 500 µm initial thicknesses, respectively. Sintering process was performed at 700• C under 2 MPa pressure for 7.5 h. Mechanical properties including the Young modulus were determined after manufacturing. The Young moduli of metallic and intermetallic phases were determined as 89 GPa and 140 GPa, respectively. Microstructure analyses showed that aluminum foil was almost consumed by forming a titanium aluminide intermetallic compound. Titanium aluminides grow up through spherical shaped islands and metallic-intermetallic interface is a wavy form in Ti-Al system. Thus, the final microstructure consists of alternating layers of intermetallic compound and unreacted Ti metal. Microstructure and phase characterizations were performed by scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. Hardness of test samples was determined as 600 HV for intermetallic zone and 130 HV for metallic zone by the Vickers indentation method.
