“…However, the literature is not conclusive on the role of interface morphology in bonding. Göbel et al (2010) and Groche et al (2014) posited that a wavy interface was not necessary to obtain a successful weld. Parchuri et al (2019) suggested that a wavy interface could improve the joint strength because of mechanical interlocking, whereas Acarer et al (2003) reported no obvious difference in strength between wavy and flat interfaces.…”

“…Since the final impact velocity could not be reached within one revolution, the rotors had to accelerate with an offset. In a former setup, the offset was realized by a phase offset of 45 • , which was compensated to initiate the collision [20,23]. After the collision, the samples are torn off at a predetermined breaking point because the rotors could not stop immediately.…”

“…After they have been joined, they are torn off their respective clamped part (left and right in figure 4) at an intended breaking point. A more detailed description of the build-up of the rest rig, a discussion of the very first results and a detailed metallographic investigation are given in [6]. Fig.…”

“…In order to simplify the acceleration and deceleration of the rotors for the phase offset technique, their moment of inertia has to be as small as possible. As described in detail in [6], aluminum tubes with a length of 500 mm are used with a fixture at each end for a specimen and a counterweight, respectively. At the maximum speed of 6000 rpm, each specimen travels at about 150 m/s and experiences a radial centripetal acceleration of about 10000 G. In the current development, the tube diameter is reduced from 20 mm to 16 mm and its wall thickness is optimized.…”
