Titanium alloys are widely used in important load-bearing components of aircraft and aircraft engines because of their high specific strength, good medium temperature performance, corrosion resistance, and good welding performance, and are an important metal structural material. According to statistics, the weight ratio of titanium alloys used in foreign aircraft has reached about 30%, which shows that the application of titanium alloys in the aviation industry has a broad future.
However, titanium alloy flange also have some disadvantages, such as large deformation resistance, poor thermal conductivity, large notch sensitivity (about 1.5), and changes in microstructure have a significant impact on mechanical properties, which leads to smelting, forging and heat treatment. Complexity, prone to defects in titanium alloy forgings.
