Ultrasonic materials processing (UMP) may produce unusual microstructural
changes in materials. However, no fundamental understanding of the
metallurgical processes in UMP is firmly established due primarily to the
complex nature of the interaction between the ultrasonic energy and the structural
changes in the material being subjected to UMP.
Unlike other deformation processes, UMP can induce high strain-rate
deformation in a material in a few seconds without altering the macroscopic
geometry of the material. High concentrations of crystalline defects, particularly
of vacancies, caused by UMP may produce unusual effects on the diffusion and
thermodynamic phase stability. This property makes UMP a unique means to
alter material structure without applying high temperature, large macroscopic
deformation or long time.
