Description

technical field [0001] The invention belongs to the field of titanium alloys, and relates to a graphene oxide reinforced titanium alloy and a preparation method thereof. Background technique [0002] Titanium alloys are usually called lightweight alloys with aluminum, magnesium alloys, etc., and the density is as small as 4.5g / cm 3 Titanium alloys are widely used in aviation, aerospace, ships, weapons, petroleum, chemical, medical and other fields. [0003] At present, the commonly used titanium alloy materials are mostly designed with high alloying of precious metal elements such as V, Zr, Pd, Ru, etc., which has high cost, complicated process, difficult processing and low yield. Graphene oxide is another two-dimensional carbon structure with an ultra-high specific surface area after graphene. Its elastic modulus can reach about 1.2TP and its fracture strength is about 129GPa. The study found that the addition of graphene can improve the mechanical properties of metal ma...
