- With the increasing use of ultrasonic measurement technology in many fields, the demand for the wideband ultrasonic transducers is also growing.
- Wave propagation in viscoelastic disk layers is encountered in many applications including studies of airborne ultrasonic transducers.
- Solid-state ultrasonic spot welding (USW) inevitably offers a potential solution for joining dissimilar metal combination like copper (Cu) and steel (SS).
- Ultrasonic features in the bonding area are of interest for researchers in the field of microelectronic packaging.
- Continuous ultrasonic in-situ monitoring for industrial applications is difficult owing to the high operating temperatures in industrial fields.
- The evaluation of sound velocity, elastic constant of thin film has not been well established.
- Ultrasonic determination of elastic properties in human craniofacial cortical bone is problematic because of a lack of information about the principal material axes, and because the cortex is often thinner than in long bones.
- Ultrasonic elliptical vibration cutting (UEVC) is attracting much attention in ultra-precision machining of brittle materials as it was found be able to effectively increase the critical depth of cut (dc) of brittle materials.
- Ultrasonic examination of anisotropic inhomogeneous austenitic welds is challenging, because of the columnar grain structure of the weld leads to beam skewing and splitting.
- The use of ultrasound for the production of nanomaterials allows a substantial improvement in access to a wide range of crystalline nano-semiconductors, but the mechanisms of ultrasound action remain largely unclarified.
- The growing field of ultrafast materials science, aimed at exploring short-lived transient processes in materials on the microsecond to femtosecond timescales, has spawned the development of time-resolved, in situ techniques in electron microscopy capable of capturing these events.
