Abstract

The invention belongs to the field of titanium alloys and discloses a graphene oxide enhanced titanium alloy and a preparation method thereof. The graphene oxide enhanced titanium alloy comprises thefollowing components in percent by weight: 0.10-0.30% of magnesium, 0.45-0.50% of graphene oxide and the balance titanium and inevitable impurities. The preparation method comprises the following steps of selecting magnesium, graphene oxide and titanium to smelt to obtain a casting blank; annealing the casting blank at 910-960 DEG C; forging the annealed casting blank into a bar at 800-960 DEG C;and carrying out aging treatment on the bar at 700-800 DEG C and insulting the bar for 1-2 hours. By making full use of solution strengthening action of Mg and neutral stability action of Mg on alphaphase and beta phase, the preparation method is simple in process and good in processing performance. The ductility of the prepared graphene oxide enhanced titanium alloy is not reduced or even is improved while the prepared graphene oxide enhanced titanium alloy is high in strength, so that a titanium alloy material has excellent strength and plasticity and can be processed into products with larger dimensions.
