How to produce high quality titanium alloy blade forging?

Titanium alloy blade forging has been widely used in aviation industry because of its excellent performance. However, the manufacture of high-quality titanium alloy blade forging is not easy, requiring strict control of the process and the use of advanced manufacturing technology. This paper will discuss how to produce high quality titanium alloy blade forging.

1. Material selection and control
   Choose the right grade of titanium alloy: According to the requirements of use, choose a titanium alloy grade with excellent properties, such as high strength, corrosion resistance, oxidation resistance, etc.
   Raw material quality control: Ensure that the purchased titanium alloy raw materials are of stable quality, free of impurities and defects, and comply with relevant standards and specifications.
   Second, mold design and manufacturing
   Mold design: According to the blade shape and size requirements, design a reasonable mold structure to ensure mold accuracy and stability.
   Mold manufacturing: The use of advanced processing equipment and manufacturing technology, such as CNC machine tools, EDM, etc., to ensure the manufacturing accuracy and surface quality of the mold.
   Third, forging process control
   Heating and temperature control: strictly control the heating temperature and heating time to avoid overburning, oxidation and other phenomena to ensure the structure and performance of titanium alloy.
   Forging process control: In the forging process, it is necessary to control parameters such as deformation degree, deformation speed and cooling speed to avoid defects such as cracks and inclusions.
   Post-treatment and heat treatment: According to the properties of titanium alloys, the corresponding post-treatment and heat treatment are carried out to optimize the performance and organizational structure of the blades.
2. Testing and quality control
   Geometric size detection: Using high-precision measuring equipment and methods, the geometric size of the blade is accurately measured to ensure that the design requirements are met.
   Surface quality inspection: check whether the blade surface is smooth, no cracks, no oxidation and other defects, improve the reliability and durability of the blade.
   Internal quality testing: Using non-destructive testing technology, such as ultrasonic testing, X-ray testing, etc., to check whether there are defects or inclusions inside the blade.
   Mechanical properties testing: mechanical properties testing of the blade, such as tensile, impact, hardness, etc., to ensure that it meets the requirements of use.
   Quality assurance system: Establish a sound quality assurance system to ensure effective quality control and management of each link in the entire manufacturing process from raw materials to finished products.
3. Personnel training and skill upgrading
   Personnel training: Training and education of manufacturing personnel on a regular basis to improve their skill level and operation standards.
   Skills improvement: Encourage manufacturing personnel to continue to learn and explore new manufacturing technologies and process methods to improve manufacturing efficiency and product quality.
   To sum up, the manufacture of high-quality titanium alloy blade forging needs to start from many aspects, including material selection and control, mold design and manufacturing, forging process control, testing and quality control, and personnel training and skill improvement. Only by fully controlling these factors can we ensure that the titanium alloy blade forgings produced have excellent performance and reliability, and meet the high requirements of the aviation industry.
