High-strength titanium alloy suitable for laser additive manufacturing and preparation method thereof

The invention discloses a high-strength titanium alloy suitable for laser additive manufacturing and a preparation method thereof. The invention relates to the technical field of high-strength titanium alloys for additive manufacturing, in particular to a high-strength titanium alloy suitable for laser additive manufacturing and a preparation method of the high-strength titanium alloy. The invention aims to improve the strength of the alloy at room temperature to the greatest extent under the condition of reducing the shaping loss as much as possible, and avoid the problems of segregation and plasticity reduction of part of alloy elements caused by various factors when a single alloy element is added. The material is composed of spherical titanium-based powder and high-temperature alloy powder. The method comprises the following steps: 1, proportionally mixing the raw materials, putting into a ball milling tank, uniformly mixing in an argon environment through ball milling, and standing in the ball milling ta
