Glass-forming ability is a long-standing concern in the field of metallic glasses (MGs), which greatly limits their maximum casting size and extensive applications. In this work, we report an ultrasonic-assisted rapid cold welding bulk MGs without using any additives. with various compositions are welded together under 20,000-Hz high-frequency ultrasonic vibration losing amorphous nature. The t...

Purpose This research aims to exploit the potential of Ultrasonic Additive Manufacturing (UAM) in the embedding of printed electrical materials directly into the interlaminar region of parts during manufacture in order to realise novel multifunctional Metal Matix Composite’s (MMC’s). Design/methodology/approach To ensure the proper electrical insulation between the printed conductor and metal m...

Ultrasonic additive manufacturing (UAM) is a rapid prototyping technology that features a metal joining process through ultrasonic welding. The bonding mechanisms and mechanics of UAM have been investigated for decades. Meanwhile, the plastic deformations of metals were extensively studied by many researchers for their significant roles in bond formation. However, most of these research efforts...

It has been acknowledged that ultrasonic impact treatment (UIT) occupies a firm position among methods for improving the reliability of welded joints, particularly their fatigue strengths. Developed in Russia in the early 1970s, this process has aroused considerable interest among experts and researchers in the area of fatigue and fabrication of welded structures. This interest reflects the ben...
