英文摘要: The invention discloses a laser direct forming process for a titanium alloy part, and relates to a laser rapid forming technology for metal powder. The process mainly comprises the following steps of determining basic process parameters of the titanium alloy part, and disclosing a new laser scanning path and a method for controlling an internal defect of a laser formed part, i.e. firstly determining a process parameter range of spherical TA15 powder by a basic process experiment, and transforming processing process parameters of different layers of the laser formed part to form the titanium alloy part by adopting the laser scanning path and the related internal defect control method, namely by adopting an optimal scanning interval. The part formed by the process has the advantages of high forming efficiency, low cost, high internal quality, high automation degree, easiness in operation and the like. The process can be used for directly forming the titanium alloy part at an industrial application level, and a novel way for the production of a titanium alloy structural part is provided.
