From: Novel twin-roll-cast Ti/Al clad sheets with excellent tensile properties
Microstructures of twin-roll-cast and annealed Ti/Al clad sheets. SEM micrographs of the cross-sectional area of the (a) as-cast specimen and (b–f) specimens annealed at 350 °C, 400 °C, 500 °C, and 600 °C for 30 min (TA33, TA43, TA53, and TA63 specimens, respectively). The interfacial reaction layer thickness is about 2.9 μm, which is thicker than that (1.2 μm) of the TA61 specimen, as shown in (g). The EDS data of the interfacial reaction layer of the TA63 specimen is shown in (h), and indicate that the layer is composed of (Ti,Mg)Al3.
