The heat treatment method of Ti45Nb titanium alloy wire includes the following steps: the Ti45Nb titanium alloy wire to be treated is placed in Muffle furnace, heated to 750 ~ 860℃ for preheating, then held for 0.5 ~ 1.6h, and then cooled to room temperature. By controlling the preheating temperature, holding time and cooling mode, the microstructure structure of Ti45Nb titanium alloy wire after heat treatment is uniform, and the comprehensive mechanical properties such as tensile strength, yield strength, shear strength and elongation of Ti45Nb titanium alloy wire are improved. It provides a good technical support for the application of Ti45Nb titanium alloy wire in the production of aviation fasteners.
As an advanced material for aviation fasteners, Ti45Nb has a density of only 5.7g/cm3. It has excellent corrosion resistance, high specific strength, good mechanical properties and machining properties, and is suitable for the manufacture of rivets for composite materials. Because the annealing temperature exceeds a certain temperature, the grain grows rapidly, which will greatly reduce the mechanical properties of the wire used for fasteners. Therefore, it is difficult to achieve the ideal matching between the structure and properties, so reasonable heat treatment process can ensure the structure and properties. In order to overcome the above problems existing in the existing technology, a heat treatment method of Ti45Nb titanium alloy wire is provided. The internal structure of Ti45Nb titanium alloy wire treated by this method is uniform, the mechanical properties are greatly improved, and the internal structure and mechanical properties of the wire are well matched.
