Abstract
Explosive welding of alternating Grade 1 titanium and AA1050 aluminium sheets produces chemically heterogeneous solidified-melt regions at all interfaces, ranging from large vortex-confined melt zones to ultrathin interfacial layers. These regions contain metastable melt-derived structures with ultrafine-grained or near-amorphous character. Using scanning and transmission electron microscopy combined with synchrotron X-ray diffraction, this study shows that annealing at 903 K transforms these regions into heterogeneous Al3Ti reaction layers. Short-term annealing promotes rapid Al3Ti formation, whereas annealing for 103 h produces a multilayer Ti–Al3Ti–Al composite with residual Al and Ti layer thicknesses of approximately 130 and 370 µm, respectively. Al3Ti growth is governed by an evolving crystallographic architecture across the reaction zone. Synchrotron X-ray diffraction and local orientation measurements reveal coupled gradients in superstructure, texture, and grain size. Fine-grained regions enriched in Al48Ti16 and Al24Ti8 develop preferentially near the Ti side, whereas coarser regions containing Al24Ti8 and D022-ordered Al3Ti form toward the centre and Al side. These findings indicate that long-term Al3Ti growth is controlled by transport anisotropy evolving across the layer thickness, rather than by diffusion through a structurally homogeneous intermetallic phase.
