When forging different grades of titanium alloys, factors such as ingot preparation, heating, forging process, heat treatment, machining, grinding, ingot number management, ultrasonic flaw detection, sawing, and sampling must be taken into account. Additionally, the forging process performance of titanium alloys is also affected by alloying elements and impurities, so it is essential to strictly control the chemical composition and impurity content.
