Paper Title:
Optimum Design, Microstructure and Mechanical Properties of Ti/Ti3Al Multi-Layered Materials
  Abstract

This study concerned with the optimum design, microstructure and mechanical properties analysis of a multi-layered metal/intermetallic materials consisting of Ti and Ti3Al prepared by the electron beam physical vapor deposition (EB-PVD) technology. Based on fracture mechanics and numerical simulation method, the optimized microstructure of Ti-Ti3Al multi-layered materials has been obtained by analyzing the relation curve between structural parameters and work of fracture of materials, then dual-target evaporating method was used to evaporate Ti and Ti-47Al bar alternately to form Ti/Ti3Al thin sheet about 0.12mm thickness. Pattern and phase analysis by SEM and XRD showed that there was homogeneous and continuous interface between layers and the intermetallic layers were made up of α2 phase alloy. The tensile curve of Ti/Ti3Al microlaminates represented the characteristic of multi-layered materials and the maximal extensibility of sample as deposited reached 5.83% and the fracture appearance showed ductile rupture feature.
