Abstract: Ultrasonic is a kind of wave with a frequency higher than 20 kHz. It is widely used in welding, cleaning, testing, ranging, disinfection and so on because of its good directivity, strong penetrability and high acoustic energy transmission. For metallic glasses (amorphous alloys) with disordered structure, the application of ultrasonic wave will make it thaw quickly and soften to a certain extent. Based on this property, we could manufacture and form metallic glasses under the beating of ultrasonic stress.

Key words: amorphous alloy, ultrasound wave, manufacture, metastable state
