非晶合金的超声制造与成型

Ultrasound manufacture and forming of amorphous alloy

超声波是一种频率高于20 kHz的声波,以其方向性好、穿透能力强、传递声学能量较高而被广泛用于焊接、清洁、检测、测距、消毒等。对于具有无序结构的金属玻璃(非晶合金)而言,其可视为被冰封的液体,而超声波的施加将在一定程度上使其迅速解冻从而软化。正是因为这一特性,在超声波的作用下制造金属玻璃并对其进行冲裁、成型等,是一种低成本、高效率制造金属玻璃材料的方法。

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.
