摘要：
In this study, the effect of the sintering time, temperature and graphene amount on titanium properties was examined for the first time in detail. From the results, the highly dense (4.39g/cm(3)), most hard (from 390HV to 566HV) and improved microstructure for 0.15wt% graphene addition were performed at 1100? for 120min. The titanium composite properties have been reduced with increasing graphene due to damaged graphene and titanium carbide formation above 0.30wt% graphene. To summarise, when pure titanium is compared with graphene reinforced titanium composites, the properties enhanced due to dislocation and fine grain strengthening mechanisms.
