Microstructure change of titanium layer in titanium/aluminium laminate metal composites during ultrasonic additive manufacturing

This paper investigates the microstructural characteristics of Ti layer in ultrasonic additive manufacturing of Ti/Al laminate composites by electron backscattered diffraction and transmission electron microscopy. Results show that a face-centred cubic (FCC) phase is formed in the Ti matrix around the Ti/Al bonding interface, and it keeps and orientation relationship with hexagonal close-packed (HCP) Ti matrix. The phase transition from HCP to FCC occurs in the region with high shear strain, which is associated with the movement of Frank or Shockley partial dislocations. The high-volume fraction of FCC-Ti under high ultrasonic amplitude can favour the improvement in the Ti/Al interfacial bonding strength via enhancing the plastic deformability of Ti foil.

期刊介绍： Science and Technology of Welding and Joining is an international peer-reviewed journal covering both the basic science and applied technology of welding and joining. Its comprehensive scope encompasses all welding and joining techniques (brazing, soldering, mechanical joining, etc.) and aspects such as characterisation of heat sources, mathematical modelling of transport phenomena, weld pool solidification, phase transformations in weldments, microstructure-property relationships, welding processes, weld sensing, control and automation, neural network applications, and joining of advanced materials, including plastics and composites.
