▎ 摘  要

The strengthening of titanium (Ti) is usually achieved by alloying it with various metal elements, in this work, we investigated a new route for the fabrication of Ti-based materials with high strength and good plasticity. Graphene produced by in situ thermal reduction from graphite oxide (GO) was used as reinforcement for enhancing the mechanical properties of the Ti matrix. A combination of ball milling, ultrasonication and freeze-drying was utilized to fabricate 0.5, 1.0 and 2.0 vol.% GO/Ti composite powders. The powders were subsequently consolidated by plasma activated sintering at 1200 degrees C for 3 min with a heating rate of 200 degrees C/min. The microstructure, mechanical properties, electrical conductivity and corrosion resistance of the prepared graphene/Ti composite materials were studied.
