TLDR
In this article, an EDS analysis yielded an interdiffusivity value of 1.9μm2/s, attributed to high strain rate (∼103−s−1) plastic deformation in aluminum, which may increase the instantaneous vacancy concentration as high as ∼10−1.About:

Thermomechanical analyses of ultrasonic welding process using thermal and acoustic softening effects
Amir Siddiq,Elaheh Ghassemieh +1 more
TL;DR: In this article, a very first attempt has been made to simulate the ultrasonic welding of metals by taking into account both of these effects (surface and volume) and a phenomenological material model has been proposed which incorporates these two effects (i.e. surface and volume).

The effect of high strain rate deformation on intermetallic reaction during ultrasonic welding aluminium to magnesium
TL;DR: In this paper, the interfacial reaction between Al, AA6111, and Mg AZ31 alloys has been studied as a function of welding energy, and it was shown that the reaction layer thickness was already ∼5μm thick.
