Sn-based lead-free solder has been widely applied in areas like electronic packaging due to
its excellent solderability. The composite solders can be obtained by mixing additional …

The synchrotron radiation technology has recently emerged as a powerful tool to
characterize the real-time microstructure evolution during solidification of alloys. Compared …

A bespoke cavitometer that measures acoustic spectrum and is capable of operating in a
range of temperatures (up to 750° C) was used to study the cavitation behaviour in three …

Ultrasonic (cavitation) melt processing attracts considerable interest from both academic and
industrial communities as a promising route to provide clean, environment friendly and …

The application of ultrasound to casting processes is a subject of great interest: the resulting
degassing, sonocrystallization, wetting, fragmentation, de-agglomeration and dispersion …

The cavitation characteristics at filler metal/substrate interface during ultrasonic-assisted
soldering were first recorded by high-speed photography in this work. Two kinds of bubbles …

Abstract Knowledge of the kinetics of gas bubble formation and evolution under cavitation
conditions in molten alloys is important for the control casting defects such as porosity and …

Currently, fundamental experimental studies in liquid metals are limited as there are very
few available experimental tools for directly measuring acoustic cavitation in such extreme …

Mg alloys were successfully bonded using Al interlayer via ultrasound-assisted transient
liquid phase (U-TLP) bonding process. The effect of ultrasonic vibration (USV) time on the …

This paper describes a series of systematic experimental studies to evaluate the
performance of a high-temperature cavitometer under well-controlled conditions. The …
