The invention discloses a method for inspecting low-magnification structural defects of titanium alloy raw materials that can detect abnormal macrostructures of titanium alloy raw materials. The method can detect tissue genetic defects caused by abnormal forging deformation of titanium alloy raw materials after ingot casting. Cut a 20mm ± 3mm thick low-magnification tissue test piece from the titanium alloy raw material, first heat it in a heating furnace at 30-40°C below the β-transition temperature for 60 minutes, then raise the power to 15-20°C above the β-transition temperature, and the furnace temperature is uniform The stability requirement is within ±5°C, keep warm for 30 minutes and then air-cool, and then observe the low-magnification structure after corrosion. This method is suitable for the inspection of the low-magnification structure of α-type, α-β-type and near-β-type titanium alloy raw materials. The judgment of the macrostructure defects of titanium alloy raw materials is intuitive and clear, and it can control the production of forgings with titanium alloy raw materials with macrostructure defects. the resulting economic losses.
