Microstructure Evolution of PtTi0.5Zr0.2/Ti Laminated Composites Synthesized by Hot Pressing and Rolling

Abstract:

The PtTi0.5Zr0.2/Ti laminated composite was prepared by hot pressing and rolling process. Microstructure, interlaminar spacing and mechanical property of the microlaminated composites after rolling were evaluated. The results showed that the layer structures of laminated composites remained consecutiveness with 93% deformation. The 12μm PtTi0.5Zr0.2 layer and 8μm Ti layer was observed finally, as well as the intermetallic compound Ti₃Pt making the PtTi0.5Zr0.2 layer and Ti layer connect with each other. Compared with Platinum and Titanium, the tensile strength of PtTi0.5Zr0.2/Ti laminated composite was enhanced by approximately 59% and 29% respectively and reached 657MPa. The tensile fracture was more uniform and showed a more coordinated process.
