Abstract
It is difficult to produce bulk blanks directly from metallic glass, which limits its application. Ni-based metallic-glass thin strips that can be manufactured easily were used to manufacture bulk metallic glass additively by ultrasonic bonding. The effects of ultrasonic vibration energy on the quality of the additive manufacturing of bulk Ni-based metallic glass were studied. The experimental results showed that a fully amorphous structure of bulk Ni-based metallic glass can be obtained with an appropriate ultrasonic vibration energy. The thermal properties were almost unchanged, and the hardness and elastic modulus of the Ni-based metallic glass were improved compared with the original material. Additive manufacturing of bulk metallic glass by ultrasonic bonding can broaden the application field of metallic glass.
