Smelting and casting process of titanium and titanium alloy

The frequency range of sound waves that people’s ears can directly receive is usually 20 Hz to 20 kHz, that is, sound (sound) frequency. The frequency lower than 20 Hz is called infrasound, and the frequency higher than 20 kHz is called ultrasonic. Several megahertz ultrasonics are commonly used in industry to detect flaws. Ultrasonic frequency is high, the propagation is strong, it is easy to propagate in the solid, and it is easy to reflect when it encounters the interface formed by two different media, so that it can be used for flaw detection. Usually the ultrasonic probe is in good contact with the surface of the workpiece to be inspected, the probe can effectively transmit ultrasonic waves to the workpiece, and can receive the ultrasonic waves reflected from the (defect) interface, and at the same time convert it into an electrical signal, and then transmit it to the instrument for processing.

According to the speed of ultrasonic propagation in the medium (often called the speed of sound) and the time of propagation, the location of the defect can be known. When the defect is larger, the reflecting surface is larger, and the reflected energy is also greater. Therefore, the size of each defect (equivalent) can be found based on the reflected energy. Commonly used flaw detection waveforms include longitudinal wave, transverse wave, surface wave, etc. The former two are suitable for detecting internal defects, and the latter is suitable for detecting surface defects, but requires high surface conditions.
