Abstract

This study proposed an in-situ reactive method that uses graphene as a reinforcement to fabricate titanium metal matrix composites (TiMMCs) through powder metallurgy processing route. The volume fraction of graphene nanoplatelets was 1.8%vol, and the pure titanium was used as a matrix. The Archimedes density, hardness, microstructure and mechanical properties of specimens were compared under different ball milling times (20 min and 2.5 h) and hot pressing temperatures (900°C, 1150°C, and 1300°C,). The ultimate tensile strength of 630 MPa, which demonstrated a 27.3% increase compared with pure Ti, was achieved under a ball milling time of 20 min. Elongation increased with increasing temperature. When the ball milling time and hot pressing temperature were increased to 2.5 h and 1300°C, respectively, the ultimate tensile strength of the composites reached 750 MPa, showing an increase of 51.5% compared with pure Ti.
